Abstract

Many researchers have been carried out in the area of bottom ash utilization in the past. In present study A mix design has been done for M30 Grade of concrete by IS method. Ordinary Portland cement of 43 Grade is selected and prepared by mixing bottom ash with cement and water for making concrete. Which is a waste material of coal firing Thermal power plants (TPPs) and its accumulation near power plant.The bottom ash is obtained from National Thermal Power Plants (NTPC) Anpara in Sonbhadra District in Uttar Pradesh state. In this paper author investigate the Compressive Strength and Flexural strength test of the concrete at different ages i.e. 7 days,14 days,28 days and 56 days. Bottom Ash is replaced 10%, 20%, 30%, 40% and 50% in the place of fine aggregate. These explain the various utilization of Bottom ash and its ordinary Portland cement and properties in concretecauses severe pollution problems. Its utilization as a raw material for cube (Brick) making will be a very usefully solution in our economical and environmental aspects. This paper presents the experimental investigations carried out to study the effect of use of bottom ash as a replacement of fine aggregate.

Keywords: Bottom ash, Cement, Coarse aggregate, concrete, sands, strengths.
