ScholarBank@NUS Repository.||Abstract:||This paper presents an experimental study to evaluate the effect of coarse and fine LWA in concrete on its water absorption, permeability, and resistance to chlorideion penetration. In additions, LWC with low unit weight of about 1300 kg/m 3 but high resistance to water and chloride-ion penetration was developed and evaluated. The results indicate that the incorporation of coarse LWA in concrete increases water sorptivity and permeability slightly compared to NWC of similar w/c. The resistance of the sand-LWC to chloride-ion penetration depends on porosity of the coarse LWA. Fine LWA has more influence on the transport properties of concrete than coarse LWA.
