This present paper reports results of a study conducted to utilize recycled fine aggregates (RFA) obtained from construction and demolition (C&D) waste, as an alternative resource of natural sand for the production of RFA based Lightweight Cellular Concrete (RLWCC). This research particularly focuses to understand the synergetic effect of foam and water dosages on the properties of RLWCC. Three differentfoam-solid ratios, 0.013, 0.026 and 0.053 and three water-solid ratios, 0.228, 0.286 and 0.325 were used in this study. The research outcome inferences that the foam and water contents have a great effect on flowability and its reduction with respect to time, bleeding capacity, microscopic void distribution, densities and strength characteristics of RLWCC. This paper elucidates the behaviour of RLWCC from the material perspective that would enhance the utilization of RLWCC in the construction sector.
