Strength performance of laterized concrete
AbstractThe results of an experimental program to investigate some characteristics of concrete containing laterite as a partial or full replacement of sand is presented in this paper. Sand in a concrete of mix ratio 1:2:4:0.56 (cement:sand:coarse aggregate:water-cement ratio) was replaced with 0%, 20%, 40%, 60%, 80%, and 100% laterite. The results show that concrete with up to 40% replacement level of sand by laterite attained the designed strength of 20N/mm2, thus indicating the possibility of using laterite as a partial replacement for sand up to this level. It was also observed from the results that the workability of laterite concrete (LATCON) increases with increase in the replacement level of sand by laterite, while the compressive, split tensile, and flexural strengths and the percentage water absorption of the concrete decrease with increase in the replacement level of sand. Regression models relating the strengths of LATCON are also presented in this paper.
