Experimental Study of Cement Mortar Incorporating Pond Ash with Elevated Temperature Exposure

Pond ash is to be investigated for its use as a partial replacement for sand in cement mortar (1:4). The effort is to be made for the utilization of Pond Ash as sand replacement material in mortar which may introduces many benefits from economical, technical and environmental points of view. The project will present the results of the cement mortar of mix proportion 1:4 in which sand will partially replace with Pond Ash as 0%, 10%, 30%, 40% and 50% by weight of sand. It is proposed to prepare two set of mixture proportions. First will be a control mix (without Pond Ash with regional fine aggregate (sand) and the other mixing will contain Pond Ash obtained from Thermal Power plant industry. The compressive strength test is to be conducted with partial replacement of Pond Ash with sand. The strength property of mortar with Pond Ash for strength at 28 days as partial replacement with the cement in the cement mortar 1:4 is to be determined. Similarly the other set of cement mortar incorporating Pond Ash is to be kept in elevated temperature up to 1100° C and tested for its compressive strength. The results for controlled cement mortar and Pond Ash mortar for compressive strength at normal temperature and elevated temperature is to be compare.
