S. Lal Department of Civil Engineering, R.C.Patel Institute of Technology, Shirpur, Dist. Dhule, Maharashtra, India Abstract— 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.

INTRODUCTION In the present study, Pond Ash samples were collected from disposal sites of Bhusawal- Thermal power plant. The effort made was to study the effect of high temperature on mortar in two sets incorporating pond ash. First cement mortar containing Pond Ash replaced with fine aggregate (0-100percentage) at normal temperature and second set containing cement mortar containing Pond ash replaced with fine aggregate (0-100 percentage) at elevated temperature. In recent years, the research and development by domestic and foreign experts have made available high-performance concrete (HPC) with high strength and high workability. The addition of fly ash and Pond Ash in order to improve workability, enhance durability, minimize environmental pollution and CO2 emission, reduce production cost and utilize resources efficiently nonetheless, research on the effect of high temperature on properties of concrete with fly ash added has been scarce but merits further study. A proper amount of fly ash would give a better and stronger concrete mixture under high temperature and pressure. Concrete containing fly ash is of a denser structure and has better fire resistance compared with that without fly ash added. This study examines the impact of pond ash addition on properties of mortar mixed at different replacement percentages and at high temperature. It is hoped tha the high-temperature properties of pond ash mortar can contribute to a better understanding of the resource recovery of pond ash and its degradation under high temperature. Occasionally, cement concrete structures are subjected to high temperatures (reactor vessels, thermal shock, fire, coal gasification vessels, some industrial applications, etc.). In most cases, such elevated temperatures result in considerable damage to cement concrete structures and masonry walls. Recently, high-strength concrete and high strength mortar are widely used in different parts of civil engineering structures. As they become more commonly used, the risk of being exposed to high temperatures also increases. Thus, better understanding of the behavior of high-strength mortar at high temperatures gains importance for predicting the mortar properties.
