MECHANICAL AND DURABILITY PROPERTIES OF CONCRETE BY PARTIAL REPLACEMENT OF CEMENT WITH WOOD WASTE ASH
Abstract :With increasing industrialization, the industrial by products (wastes) are being accumulated to a large extent, leading to environmental and economic concerns related to their disposal (land filling). Nowadays disposal of wood waste ash(WWA) generated from various sources became a very challenging problem. The present investigation mainly aimed to use wood waste ash (WWA) in structural grade concrete as partial replacement and addition to cement at various levels of 0%, 10%, 20%,25%, 30% and the use of WWA in cement concrete mix will make it cost effective and environment friendly disposal of the product. Wood waste ash is generated as a by-product of combustion in wood-fired power plants, paper mills, and other wood burning industries, in this research wood waste ash is collected from green eco ltd by the burn under several temperature of a plant species prosopis julifora and passed under 100 microns. The mechanical properties of concrete viz. compressive strength, splitting tensile strength were determined at different curing periods. The mechanical properties of wood waste ash concrete have improved at 10% of replacement of cement. Further increase in WA replacement level decreased the mechanical properties significantly Utilization of wood ash in cement and concrete was started from last 10 years.
