Utilization of sewage sludge ash (ssa)‎ as fine aggregate with local pozzolanic materials

الملخص EN

The disposal of sewage sludge from waste water treatment presents highly complex problems to any municipality, due to increasingly stringent environment regulation and industrial growth that have markedly increased the disposal requirements the incineration only reduces the volume of the sludge and remaining the sludge ash.

This study aims to investigate the effect of the substitution of cement and sand by fine sewage sludge ash (SSA) and fire air-cooled slag (FACS) separately at definite percentages.

The workability and kinetics of hydration of hardened cement mortars were studied.
