1.INTRODUCTION Foundry sand is basically high quality silica sand which is a by-product of both ferrous and non-ferrous metal casting industries. The primary metals cast include iron and steel from the ferrous family and aluminium, copper, brass and bronze form the nonferrous family. The physical and chemical characteristics of foundry sand mainly depend on the type of casting process and the industries from which it is originated. Industries use large amounts of sand as part of
As we all know now days the construction sector is exploring rapidly on a large scale and also involves new techniques for rapid and comfort works on the field. Concrete which is the main building material plays an important role in this sector. Natural resources are main ingredient of concrete which are expensive as well as on the verge of extent. So it is very important to find an alternative option. Foundry sand can be use as an alternative by replacing fine aggregate. Quarrying of aggregates leads to
