Abstract

Preparation of sand casting mould should highly considered the important mechanical properties such as green strength,and permeability.In order to determine the optimum moisture content and composition for making green sand mould,these moulding sand properties play a vital role.Moulding sand was a composition of sands,binders,and additives prior to the preparation of the sand mix. Unfortunately,foundry wastes was essentially composed of used sand mixture (about 71%), small amount of dust (approximately 12%),heat resistant materials (8%) and other wastes (9%).Moulding mixtures,represent the largest proportion of wastes.This study was all about the recycling the abrasive water jet waste to produce a sand mould.The sand mould were made of water jet abrasive waste will be mixed with silica sand as a base sand then will be compose with the other composition such bentonite,coal dust and water.Ramming process using Ridsdale-Dietert metric standard rammer to make a specimen in height of 50±0.3 mm.Each sample were undergoes permeability test using Ridsdale-Dietert permeability meter to test its permeability whilst green compression strength and green shear strength were tested by using Ridsdale-Dietert universal sand strength machine for compression test.In addition,mechanical properties such as permeability,green shear strength and green compression strength of the sand mould made of abrasive water jet waste has been analysed.The composition of 60% Silica:40% AWJW were found to have optimum green strength and effective permeability.
