An Experimental Study on Compressive Strength of Reinforced Concrete Cubes using Wheat Husk Ash&Rice Husk Ash as a Partial Replacement of Cement

In the current period of speedy transportation development, availability of costly construction materials is increasing in India. India is a crop growing based country because of its farming economy so many infrastructural changes are growing on day by day and scenario of India has been changed in the form of agricultural construction. Low cost construction materials like wheat straw ashes are to be used with concept of right amount of skills, technologies, design aids, performance of worker without degrading the quality control of materials. A series of experiments have been conducted in laboratory to compute mechanical properties of concrete like initial and final setting time of concrete, workability test, and compressive strength of reinforced cement concrete cubes for M-20 grade including wheat straw ash and rice husk ash as a partial replacement materials of cement by varying percentage of WSA and RHA. By conducting this experiment and keeping in view of an R. C. pavement with low cost materials like wheat straw ash and rice husk ash it is noticed that this low cost materials will give higher strength because wheat straw ash and rice husk ash are having high silica contents like 90 % to 95 % respectively and silica content is much more beneficial for any types of cement for gaining higher strength.
