ANALYSIS OF SAND MOLD USING INDUSTRIAL POWDERS AND FLY ASH

The greensand molding is one of the traditional ways of molding techniques usually employed for producing castings in the foundry. The main constituents of molding sand are the sand, binder and additives. The properties of the molding sand depend upon those major constituents. Since, the properties like green compression and permeability can be varied by mixing various additives with the molding sand. The casting efficiency can be improved with the help of different additives added to the greensand in the correct proportions. The main focus of our project is to make an attempt on the analysis of the greensand mold with fly ash and clay. Fly ash and clay are the additives to be mixed with the greensand and the properties like green strength and permeability are tested and tabulated. The standard specimen of AFS size is to be made with different proportions of clay and fly ash. The properties like green compression strength and permeability are checked with the help of permeability meter and Universal strength testing machine. The strategic points are to be evaluated and the aluminum castings are to be made as per the effective points.
