Abstract:

Portland cement concrete (PCC) is the world’s most versatile and most used construction material. A new method of reducing the carbon footprint and increasing the sustainability of PCC has emerged that incorporates a much larger portion of interground limestone (Type IL cement) into the cement. The objectives of this research were to characterize the fresh and hardened concrete properties of binary and ternary combinations incorporating Type IL cement. Three binary and three ternary mixtures were prepared and tested for both fresh and hardened characteristics. Concrete samples were produced in laboratory conditions with a w/cm ratio of 0.45. Fresh concrete properties measured included: slump, unit weight, air content, and set time. Hardened concrete properties measured included: compressive strength, flexural strength, surface resistivity, freeze-thaw durability, and shrinkage. The results of this study showed that the use of Type IL portland cement in Louisiana should be allowed for all applications including ternary mixtures up to 70 percent replacement. Compressive and flexural strength results were comparable. Type IL mixtures exhibited less shrinkage when compared to the control mixtures with Type I cement. Surface resistivity results were comparable and indicated that the surface resistivity meter use will be applicable for mixtures containing Type IL cement. Based upon the results of the study, the authors recommend that Type IL cements be allowed for all uses in Louisiana.
