Use of sewage sludge ash(SSA)-cement admixtures in mortars
The use of waste materials and industrial by-products in construction is well known. Scientist, engineers and technologists are continuously on the lookout for materials such as fly ashe and silica fume which can be used as substitutes for conventional cement and aggregates in concrete. The main reasons of this rising interest in using waste materials in construction are ecological, economical and technological reasons. The chemical composition of SSA (sewage sludge ash) and their sized fractions are studied, some differences in chemical composition are observed. SEM studies show irregular shape of SSA particles and sized fractions, this shape has a decisive influence on workability of mortars. The effect of replacing 15 % of portland cement by SSA and their sized fractions: coarse (SSAC) and medium (SSAM) obtained by sieving on compressive (Rc) and flexural (Rf) strength of mortars was investigated. The study reveals an enhancement of strength when ashes are used, due to probably, pozzolanic properties of SSA.
