ABSTRACT

 

This paper investigates the effect of using Partially Treated Waste Water (PTWW) on the physical properties of cement mortars collected from a Battery industry. Cement mortar specimens were casted using Deionised Water (DW) and Partially Treated Waste Water (PTWW) in six different proportions by using Ordinary Portland Cement (OPC) of 53 grade, Fine Aggregate (FA) Silica Fume (SF) and Super Plasticizer (SP). Silica fume, a mineral admixture obtained from metal and alloys industry and a Super Plasticizer, CONPLAST SP 430 were used in this investigation. DW and PTWW were analysed for pH, suspended solids, dissolved solids, alkalinity, acidity, hardness, chlorides and chemical analysis. The chemical analysis showed that the chemical compositions of PTWW were within the CPCB standard limits showing that it can be used satisfactorily in cement mortar. Soundness, consistency and setting times tests were carried out cement. Compressive strength test was carried out for 3 days, 7 days, 28 days and 90 days and durability tests were done by using 2.5% of HCl, H2SO4, NaOH, MgSO4 solutions for 30 days. The results indicated that the compressive strength of concrete of the mixtures prepared using PTWW was comparable with the DW and the results of durability tests shows that weight and strength is decreased very modestly when compared with conventional mortars
