Experimental Investigation on Concrete with Partial Replacement of Cement by Using Ash of Agro -Waste (RHA, RSA) With Cow dung Ash

The rising cost of building construction materials is the factor of great concern. We all want that our building be strong and should build with the construction material of reasonable rates. Nowadays, most of the researches are doing the research on the material which can reduce the cost of construction as well as increase the strength which waste materials are used in concrete in the replacement of any ingredient are selected according to their properties. This project paper is written to show the effect on concrete with for partial replacement of cement with cow dung as hand agricultural waste like rice husk as hand rice straw ash. Cement is replaced in concrete with ash(RHA,RSA,CDA) in various proportion by weight (like 5%, 10% and 15%) and the compressive & tensile strength of concrete were found at different curing periods (7,14 and 28 days). Various tests are conducted on samples like determination bulk density, settling time and workability of cow dung ash in different proportion. Cow dung ash (CDA) is economical in terms of cost & this reducing the environmental risk, maintaining the ecological balance.
