چکیده
|
The objective of the present research is to study the waste material obtained from the incineration of sewage sludge at 700 °c under controlled conditions,i.e. sewage sludge ash (ssa),and their influence on strength and workability of cement based mortars. the ssa was characterized chemically,physically and mineralogically. in addition,the influences of ssa on mortar properties,including workability,time of setting and compressive strength were also investigated. results show that ssa is composed of a significant amount of oxides and metals,plus an irregular morphology of its grains. the functional behaviour of mortars shows that the mechanical proprieties were moderately affected by ssa. the best mechanical results are obtained for the substitution of 10 % of ssa at 28 days.
