Tech Brief: Field Control of Concrete Paving Mixtures
Tech Brief NOVEMBER 2019 FHWA-HIF-18-013 FIELD CONTROL OF CONCRETE PAVING MIXTURES INTRODUCTION The variability of a concrete paving mixture can have a significant impact on the performance of the concrete pavement and impact its overall service life. Mixture variability can lead to inconsistent workability, poor consolidation, built-in roughness, and areas of weaker, less durable concrete, all of which can negatively affect pavement performance (Fick et al. 2012). Well-defined and implemented field control of concrete paving mixtures is extremely important to produce, deliver, and place a consistent concrete pavement mixture that meets design criteria and increases the chance of achieving durability goals. This Tech Brief summarizes guidance on the concrete-making process from batching through placement on grade. It draws from key reference documents on field control of concrete mixtures including: • Integrated Materials and Construction Practices for Concrete Pavement: A State-of-the-Practice Manual (Taylor et al. 2006). • Concrete Pavement Field Reference, Pre-Paving (ACPA 2008). • Concrete Pavement Field Reference, Paving (ACPA 2010). • Field Reference Manual for Quality Concrete Pavements (Fick et al. 2012). • Effective Quality Assurance for Concrete Paving Operations (Taylor 2016). • Design and Control of Concrete Mixtures (Kosmatka and Wilson 2016). ACPA (2008) provides a pre-paving checklist covering key items to consider and inspect during pre-paving operations, including some attributes of the concrete mixture and ACPA (2010) provides an additional checklist that focuses on all elements of the concrete paving operation itself. Together, these references serve as a good starting point to establish necessary controls to produce, transport, and place quality paving concrete. -

Team Thomas Sustainability Report 2018
Team Thomas Sustainability Report 2018 1 Introduction At Thomas Concrete Group, care for people and the environment is crucial. That’s why sustainability is and has been important to Team Thomas for a long time – a fact that is best illustrated in our Group’s Mission statement “To be the closest to customers and together actively contribute to building a sustainable society”. Our company has highly competent and committed employees who develop and produce ready-mixed and pre-casted concrete. We care and want to make a difference. Every day, members of Team Thomas wake up early in the morning, ready to serve customers at construction sites and driven by a common ambition to improve the environment around us. Together with all other companies in the construction industry, we have a great responsibility to be transparent and honest in our efforts to continuously improve sustainability performance. Every material used in construction has its own merits. Hence, it’s important to always look at the facts and proven data when making a choice. Concrete is an amazing and sustainable construction material. It is natural, beautiful and creative. Unlike most other material being used that might only last for fifty years, it could be said that concrete is a symbol of sustainability. After all, what other buildings stand for more than 2000 years like the ancient buildings in Rome have? I’m proud of what our Group has done in the area of modern sustainability, but every day we have to actively continue working to improve. Hopefully, you’ll find this report inspiring and a good way of seriously sharing what we practically do. -

Green Concrete Based on Quaternary Binders with Significant Reduced Of
energies Article Green Concrete Based on Quaternary Binders with Significant Reduced of CO2 Emissions Grzegorz Ludwik Golewski Department of Structural Engineering, Faculty of Civil Engineering and Architecture, Lublin University of Technology, Nadbystrzycka 40 Str., 20-618 Lublin, Poland; [email protected]; Tel.: +48-81-538-4394 Abstract: The article presents studies of plain concretes prepared based on a quaternary binder containing various percentages of selected supplementary cementitious materials (SCMs). The possibilities of nanotechnology in concrete technology were also used. An additional important environmental goal of the proposed solution was to create the possibility of reducing CO2 emissions and the carbon footprint generated during the production of ordinary Portland cement (OPC). As the main substitute for the OPC, siliceous fly ash (FA) was used. Moreover, silica fume (SF) and nanosilica (nS) were also used. During examinations, the main mechanical properties of composites, i.e., compressive strength (f cm) and splitting tensile strength (f ctm), were assessed. The microstructure of these materials was also analyzed using a scanning electron microscope (SEM). In addition to the experimental research, simulations of the possible reduction of CO2 emissions to the atmosphere, as a result of the proposed solutions, were also carried out. It was found that the quaternary concrete is characterized by a well-developed structure and has high values of mechanical parameters. Further- more, the use of green concrete based on quaternary binders enables a significant reduction in CO2 emissions. Therefore quaternary green concrete containing SCMs could be a useful alternative to plain concretes covering both the technical and environmental aspects.

Field Monitoring of Shrinkage Cracking Potential in a High
FIELD MONITORING OF SHRINKAGE CRACKING POTENTIAL IN A HIGH-PERFORMANCE CONCRETE BRIDGE DECK By TIM WALKOWICH A Thesis submitted to the Graduate School – New Brunswick Rutgers, The State University of New Jersey in partial fulfillment of the requirements for the degree of Master of Science Graduate Program in Civil and Environmental Engineering Written under the direction of Dr. Hani Nassif and approved by New Brunswick, New Jersey January 2011 ABSTRACT OF THE THESIS Field Monitoring of Shrinkage Cracking Potential in a High- Performance Concrete Bridge Deck Thesis Director: Dr. Hani H. Nassif Over the past decade many state engineers throughout New Jersey have reported cracking on High Performance Concrete (HPC) bridge decks at early ages. The presence of cracking early in the life of a high performance deck offsets the benefits gained in using the material as the potential for corrosion begins at the onset of cracking. While many factors apply to bridge deck cracking, the shrinkage of the concrete’s mass is a primary concern. Because of shear studs and boundary conditions, among other causes that act in restraining the deck itself, it is important to understand the mechanics of concrete under restraint. The AASHTO Passive Ring Test (PP 34-06) is seeing an increase in use in studies analyzing restrained shrinkage. The test simulates a concrete member of infinite length and allows researchers to study the effects of various parameters on restrained shrinkage. This thesis presents the results of a study that analyzed the ring test’s ability to simulate restrained shrinkage on HPC bridge decks. The investigation incorporated an instrumented, simply supported ii composite bridge deck with laboratory samples taken on the day of the pour as well as a finite element analysis.
