Evaluation of Various Coarse Aggregate Concretes
It was the purpose of this project to make a complete determination of the various properties of plastic and hardened concrete, to the extent of the laboratory's capabilities, using coarse aggregates, such as sandstone and limestone. The properties of these mixes were then compared with the properties of the presently used Class A gravel concrete. This data will serve as a bench mark for any future use of concrete mix using these coarse aggregates. Mix property information will be on file. The scope of the project was accomplished by a laboratory evaluation of a number of mix designs, totaling fifty-four, with variables including type of aggregate, cement content, mix type, and admixture type. Material properties determined included: compressive strength, flexural strength, splitting tensile strength, abrasion resistance, length change, time of set, resistance to freezing and thawing, scaling, 90 day permeability, absorption, slump, air content and unit weight. Evaluations were also made on the cost and the availability of these coarse aggregates.
