USE OF AGRICULTURAL WASTE MATERIAL WHEAT HUSK ASH AND CRUSHEDSTONE DUST IN DESIGN MIX CONCRETE BLOCK

Abstract

In this modern age the utilization of cement as Concrete is used commonly for the construction of buildings,highways, Bridges,Dams, Tunnels and Various large structures. The shortage of conventional material due to increased use of concrete ingredients has an important role in increasing the price of housing. Wheat husk ask is an agricultural waste material which is burnt to form powdered ash.The Pozzolanic property of wheat husk ash which helps to partially replaceof Cement and sand in concrete M25 mix design. The replaced material of wheat husk ash and Crushed stone dustcan be used in M25 design mix of cement concrete with desired proportion percentage of such as 0%,10%,20%,30%,40% and 50% along with Ordinary Portland Cement of grade 43,to investigate the strength parameter of concrete block are Workability, Compressive strength ,Flexural strength and Tensile strength.Thusthe resultwere compared with those of normal concrete with w/c ratio 0.50 keeping constant in all the concrete mixes. Compressive strength, flexural strengthand split tensile strength of the concrete mixes used in this experiment has been obtained after 7 days, 14 days and 28 days. The results of the experimental work showed that replacement of Cement with Wheat husk ash and Fine aggregate with crushed stone dust increased up to40% of compressive strength, up to 30% of split tensile strength and flexural strength of concrete block. These results were shown in the utilization of Wheat husk ash and crushed stone dust in construction industries for the
manufacturing of concrete block
