PARTIAL REPLACEMENT OF COAL GREY BY FINE AGGREGATES

In this present journal investigate an attempt is to be partial replacement of coal grey by fine aggregates used in constructions. All over the world sand should be normally available. The new type of construction materials to be provided to high strength and reduce the self - weight of the structure. In Design of light weight concrete are reducing the density and economic benefits achieved if waste materials can be used to replace the fine light weight aggregates. The new sources of aggregates which is produ ced from industrial wastages. The use of structural grade light weight and helps to construct largest precast units. These materials increasing demand for light weight aggregates and their limited availability of naturally occurring materials. Large scale industries are production of light weight aggregates are started after world war - 1. The main forte of this concrete is low density and thermal conductivity. Ultimately there are reduction of dead load, lessen handling cost.
