Effect of Use of Waste Foundry Sand in Concrete

Now-a-days the construction sector is exploring rapidly on a large scale and also involves new technique for rapid and comfort works on the field. Concrete as a building material plays an important role in this sector. The consumption of natural resources as ingredients of concrete cost high as well as it is on verge of extent. These problem force us to recover the natural resources or to find an alternative option to overcome this problem. Presently, the production of waste foundry sand as a byproduct of metal casting industries causes various environmental problem. usage of this waste in building material would help in reduction of stress on environment
