The researchers have shown that for every 600 kg of cement, approximately 400 kg of CO2 is released into the atmosphere. The increasing demand of cement leads to higher rate of environmental degradation. Scarcity of land-filling space and because of its ever increasing cost, recycling and utilization of industrial by-products and waste materials has the only option. The utilization of such materials in concrete not only makes it economical, but also helps in reducing disposal concerns. Wood ash is the residue produced from the incineration of wood and its products. Wood ash has been used as a replacement of lime or cement kiln dust in the solidification of hazardous wastes. An experimental investigation is carried out to study behavior of M50 concrete using wood ash as a partial replacement for OPC 53 grade cement is partially replace with 0%, 5%, 10%, 15% and 20% and polycarboxylate based super plasticizer is added to concrete. Concrete cubes, cylinders and beams will be cast and test on it. Main aim is to determine the effect of wood ash as partial substitute of cement on the properties of concrete in fresh state and hardened state. Hardened concrete test like compressive strength at the age of 7 days, 14 days and 28 days will be obtain and also durability aspect of wood ash concrete for sulphates attack will test.
