Abstract

The present study explored the technological feasibility of re - using sewage sludge ash (SSA) as a Portland cement replacement in commercially manufactured pre cast c oncrete blocks. The blocks anal ysed were made to the guidelines laid do wn in Waste Water T reatment Plant Sludge, and Indian specifications (CE marking) for such products. Performance was compared in three families of blocks, with 0, 10 and 20% SSA. The findings proved that SSA is apt for pre cast concrete b lock manufacture and that, in addition to the economic and environmental benefits afforded, its use would improve certain of the properties of conventional block
