ABSTRACT: Generally, the use of LWA in concrete lowers its density and therefore reduces the overall dead weight on the entire structure resulting to lower cost of the structure. This paper is an overview of the performance of scoria as aggregate in concrete and behaviour variety of different additives in the composite in an effort to improve its properties. The performance of scoria aggregate in concrete was found to be highly appreciable and could be improved by controlling the water content, pre-soaking, silica fume and fly ash.
