Abstract: In this paper, compressive strength of concrete and water sorptivity of concrete partially replace aggregate by light weight fly ash aggregate in different ratio were studied. Different percentage of lightweight fine aggregate (LWFA) and a constant amount of lightweight coarse aggregate (LWCA) and were used to yield the concrete. Various amounts of LWFA were achieved by volumetric substitution of fine aggregate, six different replacement levels as, 0%, 25%, 50%, 75%, and 100% were utilized. Hence, in this experimental study six various concrete mixtures were produced. Steam curing method was applied to the concrete production. At first steam curing (SC) is exposed to concrete productions, and then the samples were moved to water until testing date. Enhancement of water sorptivity test was conducted at 28 days and 56 days. And enhancement of compressive strength test was applied over 56 days.
Keywords: Fly ash, Lightweight Aaggregate, Sstrength development, Water Sorptivity.
