Abstract
The present research aims at investigating the influence of lightweight expanded clay aggregate (LECA) on properties of high workability concrete. In the experimental, natural coarse aggregate (crushed limestone) was replaced by the LECA at replacement ratio of 16, 32, and 47 percent (by weight), while the control concrete mixture contained only crushed limestone as coarse aggregate. Concrete properties investigated in this work included slump flow of fresh concrete, and density, compressive strength, and autogenous shrinkage of hardened concrete. Test results revealed that the replacement of crushed limestone by the LECA led to the increase in slump flow spread, and the decrease in density and compressive strength of the concrete. Concrete with 32% LECA exhibited the highest slump flow spread and 28-day compressive strength. Concrete with 47% LECA had the lowest density which is 18.7% lower than that of the control mixture. It was also found that concrete with 32% and 47% LECA resulted in higher autogenous shrinkage in 28 days, as compared to the control concrete.
