Investigation of Strength of Concrete Containing Locally Available Industrial and Agriculture Waste

This paper presents the experimental study undertaken to investigate the influence of partial replacement of cement with Fly Ash (FA), Rice Husk Ash (RHA) and Sand with Stone Dust (SD). Fly ash is a by-product of burned coal from power station, stone dust is a by-product of crushed aggregate and rice husk ash is a by -product of burned rice husk at higher temperature from paper plant and other industries. Waste disposal is an important issue in the present time and utilization of Industrial waste Fly Ash, Stone Dust and Agricultural waste -Rice Husk Ash in concrete making is being researched. Considerable efforts are being taken worldwide to utilize natural waste and by -product as additional cementing materials to improve the properties of cement concrete. Stone Dust (SD), Rice Husk Ash (RHA) and Fly Ash (FA) are such materials. This study is carried out by keeping 20 % replacement of cement by FA in all the mixes and then replacing cement and sand by RHA and SD respectively by different percentages. This study shows that 10 % RHA+20 % FA and 30 % SD in concrete gives maximum strength.
