Abstract

In this study, sediment from louver edge process (LES) was used as a fine aggregate in autoclave aerated concrete (AAC) with various replacement levels (0%, 25%, 50%, 75%, and 100%) and pulverized fuel ash (PFA) was used to replace for ordinary Portland cement (OPC) at the level of 80% by weight. AAC samples were subjected to steam curing at 180„aC for 8 hours. The physical, mechanical and microstructure properties of AAC were examined. Results showed that the unit weight and compressive strength decreased with increasing the amount of LES. Scanning electron microscopy (SEM) reveals the presence of platy tobermorite in the reference sample but at increasing amount of LES, lath-like tobermorite and fibrous CSH were formedThis electronic document is a ¡§live¡¨ template.
