Replacement of Coarse Aggregate with Sintered Fly Ash Aggregates for Making Low Cost Concrete

The present research establishes a relationship of bulged diameter with densification and hydrostatic stress in forming of sintered fly ash. In present study A mix design has been done for M25 Grade of concrete by IS method. Ordinary Portland cement of 43 Grade is selected and sintered fly ash aggregates were prepared by mixing sintered fly ash with cement and water for making low cost concrete. Which is a waste material of coal firing Thermal power plants (TPPs) and its accumulation near power plant.The sintered fly ash is obtained from Gallant group of industries. This industry is located near Sector-23, GIDA Sahjanwa city in Gorakhpur 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. 3 days, 7 days, 14 days, 28 days, 56 days and 90 days. Sintered Fly Ash Aggregates is replaced 10%, 20%, 30%, 40% and 50% in the place of Corse aggregate. These theses explain the various utilization of sintered fly 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.
