PART 1 GENERAL 1.01 SUMMARY A. Description: 1. The work covered by this section includes the supply of concrete unit masonry. B. Definitions: 1. Admixture: Substance other than prescribed materials such as water, aggregate and cementitious materials added to concrete to improve one or more chemical or physical properties. 2. Ashlar: A masonry unit that is half the height of a standard unit. 3. Block (also concrete block): A solid or hollow unit larger than a brick sized unit. 8. Bond Beam unit: a U or W-shaped masonry unit, placed with the open side up to accommodate horizontal reinforcing and grout to form a continuous beam. Also known as a channel or lintel block. 5. Bull-nose units: a masonry unit with one or more rounded corners to soften corners. When there are two rounded corners on the same face of the block, it is referred to as a pilaster bullnose. When there are two rounded corners on the same end of the block, it is referred to as a double bullnose. 3. Concrete Masonry Unit: Hollow or solid masonry unit, manufactured using low frequency, high amplitude vibration to consolidate concrete of stiff or extremely dry consistency. 4. Efflorescence: A deposit of encrustation of soluble salts (generally white), that may form on the surface of the masonry unit when moisture moves through the masonry materials and evaporates on the surface.

  • STRENGTH of CONCRETE MASONRY UNITS with PLASTIC BOTTLE CORES by SEAN M. WONDERLICH B.S., Kansas State University, 2014 a THESIS
    STRENGTH OF CONCRETE MASONRY UNITS WITH PLASTIC BOTTLE CORES by SEAN M. WONDERLICH B.S., Kansas State University, 2014 A THESIS submitted in partial fulfillment of the requirements for the degree MASTER OF SCIENCE Department of Architectural Engineering and Construction Science College of Engineering KANSAS STATE UNIVERSITY Manhattan, Kansas 2014 Approved by: Co-Major Professor Kimberly Waggle Kramer, P.E., S.E. Approved by: Co-Major Professor Bill Zhang, PhD., P.E., S.E., LEED AP Copyright SEAN M. WONDERLICH 2014 Abstract Concrete masonry units are a common method of construction in the world. Since the masonry units can be constructed with ease. Fifty billion water bottles are consumed every year. Lack of waste management and recycling in third world countries has come to the attention of many organizations. The use of plastic bottles in construction materials has been around for the past twenty years, but with little focus on using full plastic bottles in the materials. The Engineers Without Borders student group on the campus at Kansas State University have found a way to utilize the full 500-mL plastic bottle in the creation of concrete walls. The bottles laid horizontally with concrete on both sides and as mortar between the bottles was used. These bottles create large voids in the wall decreasing the compressive strength of the wall. This thesis presents the results of a study conducted to determine the compressive strength of concrete masonry units with plastic bottle cores. The plastic bottles were used to create the center voids in the masonry units. Concrete was placed around the bottles to encase them in the masonry units.

  • High SCM Grout Phase 2 and 3 Research
    Engineering Notes For Design With Concrete Block Masonry M A S O N R Y Winter C H R O N I C L E S 2010-11 are a viable alternative for concrete masonry construction, with significant sustainable and economic benefits. For these high SCM grouts, it is recommended that the grout compressive strength be tested and evaluated at 42 days rather than 28 days. Introduction Concrete masonry has many sustainable benefits. Among them are its: • long life cycle, • durability/low maintenance requirements, • structural capacity (ability to withstand earthquake and high wind events), • sound-proofing, Grout PlacementMasonry Unit in ConcreteCells • fire-proofing, • insect-proofing, • ability to provide a finished architectural surface (which eliminates the need for . paints or other coatings), • ability to incorporate recycled materials, and • recyclability at the end of a building’s life. HIGH SUPPLEMENTAL CEMENTITIOUS In addition to these benefits, the industry MATERIAL (SCM) GROUT continues to investigate potential improvements. PHASE 2 AND 3 RESEARCH One such area is reducing the use of Portland cement in concrete masonry construction. Abstract Portland cement is an integral part of all concrete products, including concrete masonry units, Reducing the amount of Portland cement used mortar and grout. Portland cement acts as a in construction has important environmental structural binding agent: through the hydration benefits in terms of both the energy used to process, the cement and water harden and bind manufacture the cement as well as in lower the aggregates into a cohesive structural unit. CO2 emissions. To improve the sustainability of concrete masonry construction, research Portland cement production, however, was conducted to determine the viability of generates almost one ton of carbon dioxide replacing up to 80% of the Portland cement in for every ton of cement produced.
