The results indicate that incorporation of pre-soaked coarse LWA in concrete increases water sorptivity and permeability slightly compared to normal weight concrete (NWC) of similar water-to-cementitious materials ratio (w/cm). Furthermore, resistance of the sand-lightweight concrete (LWC) to water permeability and chloride-ion penetration decreases with an increase in porosity of the coarse LWA. The use of fine LWA including a crushed fraction||Source Title:||Cement and Concrete Composites||URI:||http://scholarbank.nus.edu.sg/handle/10635/84562||ISSN:||09589465||DOI:||10.1016/j.cemconcomp.2010.08.005|
