WWW.ICRI.ORG MARCH/APRIL 2020 CONCRETE REPAIR BULLETIN 11 Approach to Preservation of Historic Concrete by Ann Harrer, Paul Gaudette, and Deborah Slaton

Primary causes of concrete deterioration are usually related to corrosion of embedded metal, freezing and thawing of critically saturated concrete, materials problems, issues related to original construction, structural issues, and inappropriate past repairs. The nature and severity of deterioration also depends upon the climate and other conditions of environmental exposure (such as pollutants and/or chlorides).1

To address distress and deterioration of a historic concrete structure, a rehabilitation strategy should be developed that accounts for the significance of the concrete structure, preservation goals, and limitations on repairs and modifications that need to be addressed as part of the repair design. While similar processes and procedures are utilized for the assessment and repair of any concrete structure, additional considerations pertain to work on architectural and historic structures. Often the approach to repairs may be complicated due to the original construction methods, need to match an exposed finish, conservation requirements for historic fabric, or other factors. These challenges are becoming more apparent as important early twentieth century and Modernist concrete structures from the 1930s through the 1960s are undergoing rehabilitation.

John J. Earley’s work exemplified the creativity and aesthetics that can be achieved by utilizing exposed aggregates in architectural precast panels (Fig. 1). Architects such as Frank Lloyd Wright, Le Corbusier (Fig. 2), Louis Kahn (Fig. 3), and many others incorporated concrete as architectural elements in their designs.

ASSESSMENT It is important to note that historic structures designated or listed at the federal, state, or local levels will be subject to governing standards and requirements for reviews associated with preservation and rehabilitation. The goals and expectations for a rehabilitation strategy and maintenance program that is sensitive to the historic characteristics of the structure should be established with the owner at the beginning of the project.

The initial step in the development of a rehabilitation strategy is an assessment to evaluate existing conditions Fig. 3: Exposed concrete finish at the Salk Institute for Biological Studies in La Jolla, California, designed by Louis Kahn

Field Investigation The next step is to perform field investigation and testing.4 The investigation starts with a visual condition survey and comparison of the as-built construction with the gathered documents and information, and documentation of the existing conditions of the concrete, including the structural and architectural elements and the original concrete finish and texture. Coatings or membranes applied to the concrete and the condition of these systems should also be investigated and documented (Fig. 8). The condition survey can also yield information about original construction such as placement techniques and finishing procedures, as well as potential construction deficiencies including poor consolidation of the concrete during placement. Fig. 4: Exposed concrete surfaces and sculpture at the Bailey Magnet School, Jackson, Mississippi Field investigation of the concrete often includes various types of nondestructive testing, inspection openings, and removal of concrete samples for laboratory studies. The reinforcement embedded within concrete often requires investigation beyond the visual survey to understand the as-built construction and to verify information shown in construction documents. Nondestructive evaluation can provide some information regarding the location of reinforcement, properties of the concrete, and the location and extent of distress; however, selective inspection openings are necessary to confirm the findings of nondestructive evaluation.5

Inspection Openings As conditions that contribute to deterioration and distress within concrete structures are often not visible, the use of inspection openings can verify conditions from the visual survey, sounding, and nondestructive testing. Locations Fig. 5: Exposed aggregate at a historic concrete balustrade for inspection openings should be representative of the various conditions noted during the survey and should be unobtrusive if possible, especially on historic structures. Locating inspection openings in areas of existing distress (cracks or spalls) can provide information while minimizing the removal of material (Fig. 9).

Laboratory Studies Laboratory studies provide information on the characteristics of the concrete and causes of deterioration that are especially important in repair of historic concrete. Sam- ples, preferably concrete cores of the size as required by ASTM C42,6 or as required for other laboratory testing, can be removed from representative locations. If concrete core samples cannot be obtained due to access, architectural sensitivity, or other limitations, fragments or incipient spalls can yield information, although limited by the un- controlled nature of a fragment. Additional information on Fig. 6: Variations in formwork and finish at a historic concrete facade available laboratory testing is provided in ACI 364.1R-19.4

14 CONCRETE REPAIR BULLETIN MARCH/APRIL 2020 WWW.ICRI.ORG Petrographic examination (ASTM C856),7 the detailed analysis and study of concrete using stereomicroscopy, provides valuable information regarding concrete compo- sition, original concrete mix, and potential causes of ob- served distress. Information gathered through materials studies helps identify causes of distress and also assists in the development of the repair design, such as specify- ing compatible and aesthetically matching concrete mixes.

CONSERVATION APPROACH Through evaluation of the assessment findings, taking into consideration the owner’s project goals, a conservation approach can be developed that addresses existing deterioration while being sensitive to the preservation of the historic fabric. Fig. 7: Ongoing condition assessment of a historic concrete building facade The conservation approach needs to consider technical issues, characteristics of the original concrete, and aesthetic considerations such as matching the original concrete elements. Similar to any assessment, the findings are studied to determine the underlying causes of ob- served deterioration and distress to develop an appropriate scope and extent of repairs. The owner’s intended use and maintenance of the structure, as well as the significance of the structure, should also be understood. In some cases, structural assessment and analysis may be necessary. Most importantly, the conservation approach should address the underlying causes of the distress or deterioration of the concrete to minimize continued deterioration or premature failure of the repairs.8

Repairs to the concrete should be durable and extend the service life of the concrete structure. It is therefore important that the repair approach includes surface preparation of the substrate to achieve bond of the repair material to the original concrete substrate. This may require removal Fig. 8: Due to variations in formwork and finishing techniques, there are visible dif- of some historic fabric as part of the repairs, such as where ferences in texture, even after a coating has been applied removal of concrete to access all sides of a corroded bar is necessary to mitigate ongoing corrosion and to key-in and mechanically anchor the repair to the substrate concrete (Fig. 10). The characteristics of the original concrete should be considered in selecting the repair material and design- ing the repair.9 For example, the compressive strength and modulus of elasticity of the repair material need to be compatible with the original or substrate concrete. In addition, the depth and shape of the repair should be selected to provide durable service life for both the repair and the substrate concrete.

Because the exterior facade of historic concrete structures is often exposed concrete, the conservation approach should also consider matching the existing overall aesthetic of the concrete including color, texture, and finish. Research and consideration of available cements, aggregates, and potential admixtures to develop a compatible mix that is a match to the original in color and texture is necessary. Locally available materials may have been Fig. 9: Delamination and spalling at exposed concrete are examples of distress and used during original construction and may be available for deterioration that should be documented as part of a visual condition survey

18 CONCRETE REPAIR BULLETIN MARCH/APRIL 2020 WWW.ICRI.ORG function and safety of the building envelope as well as its aesthetics.

Nearly ten years after the “Hoosier Celebration ‘88” beautification project, a façade assessment was performed after a large limestone shard fell off the building and damaged a vehicle parked below. This 1999 assessment identified multiple loose limestone shards across the stone washes throughout the façade which were epoxied in place as part of an emergency repair program. In 2005, a larger scale maintenance repair program was performed to address masonry repairs throughout the main façade as well as the rotunda and lantern components of the building. In 2016, a complete building envelope assessment was performed and a phased repair program developed to address anticipated work items over the next 20 years. Prior to the start of the assessment, the owner’s Fig. 2: Loose limestone shards located at existing drive pins used to secure the representative suggested that the study “is not about what metal flashing to the stone we know, it’s what we don’t know about.” As observations began, it became readily apparent how accurate that statement truly was.

2016 ASSESSMENT: CRITICAL FINDING In 1976, somebody thought they were doing it right by installing the sheet metal flashings over the limestone with lead-coated steel drive pins. Unfortunately, time would tell how troublesome plain carbon steel anchors can be in a historic masonry structure. In 1999, the emergency repair program addressed loose limestone shards at approximately 30% of the drive pins. By 2005, the number of repairs increased to nearly 40%. Some ten years later and with over $900,000 USD in repairs performed, the number of drive pins which had required repair topped 75% (Fig. 2 and 3). Who would have ever thought that such a simple and commonly used fastener could cause such damage? Based on the exponential increase in loose shards between the 2005 repair work and the 2016 assessment, it was clear that a more comprehensive repair Fig. 3: Loose limestone shard along raked edge of gable feature needed to be implemented rather than addressing the individual shards in place.

The stone failures were attributed to the corrosion of the lead-coated steel drive pins that were used to secure the metal flashings to the limestone (Fig. 4). From historical records, it appears that most of the current metal flashings dated back to the 1976 roofing project. At that time, it was customary to install such flashings with drive pin fasteners directly into the stone substrate. After removing some of the loose stone shards, the pin was exposed and the lead jacket around the pin had some white salts on the outer surface; however, most of the corrosion that led to the stone failures was attributed to the carbon steel pin inside the jacket (Fig. 5). In addition to the expansive corrosion forces from the pin, another factor affecting the stone failures was the location of the pins in the stone. The edge distance from the fastener to the face of the stone was typically less than 2 in (50 mm) as shown in Figure 6. Fig. 4: Loose shard was removed to expose corroded drive pin fastener

WWW.ICRI.ORG MARCH/APRIL 2020 CONCRETE REPAIR BULLETIN 19 During the course of the work, one metal flashing system on the building was found to have been constructed without the use of metal drive pins. Not surprisingly, the limestone throughout that wash was in good condition. The lack of loose shards at those locations was attributed to the screw fastener detail installed to secure the wood blocking underneath the sheet. Those flashings and adjacent stone did not require repairs as part of the work.

Based on the findings, two facts became evident. First, drive pin anchors installed in masonry with insufficient edge distances will likely result in eventual localized failure of the masonry. Second, the period of time that it takes before corrosion of the drive pin progresses to the point of masonry failure may be 40 years or longer. To that point, leaving the existing metal flashing and drive pins in Fig. 5: Corroded steel drive pin still attached to removed sheet metal flashing place was not a long-term solution given the widespread segment after lead jacket removed damage that had occurred within the limestone. The drive pins needed to be removed and alternative flashing options considered.

ALTERNATIVE FLASHING OPTIONS Two different flashing options were presented to replace the existing drive pin anchored flashing system. The first option included a new lead-coated copper flashing assembly with a treated wood blocking base fastened to the limestone wash with stainless steel threaded rod epoxy anchors. The anchors were roughly centered in the wash to provide sufficient edge distance and the Type 304 stainless steel provided the necessary corrosion resistance. The wood blocking allowed for the new flashing cleats to be installed without any mechanical anchorages into the limestone.

A modern alternative was considered for the second flashing option. All metal and mechanical anchorages Fig. 6: Drive pin in limestone not yet removed (note the proximity to the outside were eliminated and a polymethyl methacrylate (PMMA) face of the stone) liquid reinforced flashing system was directly adhered to the limestone masonry. This system was reinforced with polyester fleece at each of the mortar and Dutchman joints in the limestone. The 3-course reinforced liquid system was top coated with an ultraviolet-stable tinted finish coat pigmented to match the buff-colored Indiana limestone on the building.

The exterior repair program that followed the assessment was broken into four separate phases. As part of the first phase, both flashing options were included so they could be further evaluated. Prior to the installation of either system, the existing metal flashings and drive pins were removed from the building. Dutchmen (limestone pieces used to repair the damaged limestone substrate, sized and shaped to fit a precise cavity that is carefully created by the installer) were installed across the limestone washes and gables to address the widespread loose shard damage (Fig. 7). The Dutchmen were detailed to match the original Fig. 7: New limestone Dutchman installed at stone wash to address closely spaced stone profiles. Following the stone repairs, both of the loose shard damage proposed flashing systems were installed at different

The relative humidity is kept between 40 and 60%

22 CONCRETE REPAIR BULLETIN MARCH/APRIL 2020 WWW.ICRI.ORG during summer and 35 to 40% during winter. After years of service, firms were hired to assess the condition of the envelope. It was noticed that the insulation and the vapor barrier installed were not enough to prevent condensa- tion. On the outside, the shell is exposed to temperatures ranging from -13 to 86°F (-13°F = -25°C) and relative humidity between 55 to 95%.

Degradation mechanisms were identified in the concrete shell (Fig. 6 through 8). These degradations, such as the corrosion of the anchor plates, could reduce the service life and safety of the structure. Before the preservation project, actions were taken to minimize risk, but they were not enough to prevent and control the degradation.

THE PRESERVATION PROJECT In 2014, to address the deterioration of the concrete shell of the theater, the Grand Théâtre de Québec solicited a Fig. 2: The inner structural theatre frame design-build solution that would respect the original design concept of the award-winning architect, Victor Prus, and preserve the integrity of the mural made by Jordi Bonet.

Project Requirements The proposed solution had to: • Extend the service-life of the structure by 50 years; • Use quality material with minimal maintenance for the next 50 years; • Provide protection against the elements (meaning the freezing) and remove the dew point from the walls; • Stop the ongoing concrete degradations; • Preserve the in-house temperature and relative humidity; • Not disturb the ongoing activities, including shows and practices (the contractor had to limit the vibration and noise during the demolition work); and • Preserve the mural and the exterior appearance. Fig. 3: The outside prefabricated concrete shell is installed

The Team The selected consortium was led by a general contractor and the concept was designed by a joint venture between two architectural firms. An engineering firm was responsible for the structural, mechanical, and electrical design aspects. Another engineering firm was in charge of the glass casing design. Finally, an engineering firm specializing in concrete repair and durability was involved to control the degradation and validate the 50-year service-life extension.

The Concept Many solutions were investigated. However, to prevent any damage to the mural, the best solution was to install an oversized climate-controlled glass casing to protect the concrete from the elements and prevent further deterioration. A new protective shell was added as a design conti- nuity of the first protective shell to improve the building’s exposure conditions, a radical and permanent solution unique in North America.

The idea is to catch the fresh air from outside and bring it in to the glass casing and heat it if needed (Fig. 9). Temperature management within the casing would be adjusted by pushing cold air to hot areas during the summer and warmer air to cold areas during the winter. The goal is to keep the temperature between 37 to 39°F (3 to 4°C) during winter and below 104°F (40°C) during summer. (b) Because major degradation mechanisms affecting the structure were strongly correlated to the concrete saturation, the protection was designed to reduce the water content. The goal was to keep a relative humidity of 20% in the tempered zone between the concrete and the glass shell during the winter and less than 70% during summer. Nu- merical modeling was performed to validate that the tempered zone could reduce the water content in the concrete below the critical level. According to analysis, the proposed solution can reduce the water saturation below the critical level of 80% in less than 5 years.

Restoration Program and Assessment Localized concrete repairs had to be performed on the existing envelope. For a good compatibility between the materials, a comprehensive

EXISTING CONCRETE STRUCTURES—LEARNING LESSONS AND ADVANCING SOLUTIONS ACI Committee 562, Evaluation, Repair, and Rehabilitation of Concrete Buildings, strives to advance the practice of engineering and improve the repair and rehabilitation of existing concrete structures. ACI Subcommittee 562-E, Edu- cation, is dedicated to helping engineers, building officials, contractors, owners, inspectors, and others by conveying information in more detail than is possible solely through the ACI 562 Code and Commentary. To this end, and in the hope of improving these documents, members of ACI 562 are providing a series of articles under the main theme, “Existing Concrete Structures—Learning Lessons and Advancing Solutions.”

Through this series, the committee members explain the rationale behind some of the changes in the ACI 562-16 Code as well as share example problems, ideas, concepts, and the thoughts discussed in ACI Committee 562 meetings. It is also anticipated the series will help the committee address questions from the engineering and construction sectors, solicit answers to problems, and review areas of needed research.

Field work is tests do not determine the ultimate strength. In general, an essential component of the assessment and typically load testing can be used to: involves performing visual and tactile surveys, obtaining or verifying as-built information of the structure, conducting • Determine the ability of a structure to carry additional nondestructive testing (NDT), or extracting material loads; samples for laboratory testing.

These improved or calibrated models allow for a more thorough interpretation of the test results.

COMPARING LOAD TESTING REQUIREMENTS Fig. 1: Load testing of stadium grandstands using drums filled with water The load testing requirements in ACI 437.2-13 and Chapter 27 in ACI 318-14 have slight differences. The committees responsible for these standards are working to reconcile the differences so that the test protocols and acceptance criteria are the same regardless of the structure’s classification as existing or new construction.

The monotonic load testing procedures in ACI 437.2 and ACI 318 are similar, and the acceptance criteria in both codes are based on the maximum measured deflection and the amount of deflection recovery. However, the standards specify different limits for the maximum measured deflection for monotonic load testing. ACI

437.2 specifies the maximum deflection of lt /180, where

lt is the span of the element under load test. If this limit is exceeded, the standard rules out retesting or the option of using deflection recovery as an acceptance criterion. 2 ACI 318 specifies the maximum deflection of lt /20,000h, Fig. 2: Load testing of a concrete slab in a parking garage using hydraulic rams where h is the overall element thickness.
