The study of the conditions needed to transform the wastes emerged by granite sawmills to the glassystate


Abstract in English

This study ains for the ability of using granite waste emerged by sawing granite in Syria, which is considered as a negative effect on the environment , which pollutes the air , people, animal and planit. The chemical composition of granite waste was defined and it was clear that it is same as the chemical composition of glass . so we did this work by transforming the waste caused by granite sawmills to the glassy state. The preparation for the glassy states were done py two methods , the first by adding sand and sodium carbonate and second by adding borax and sodum cab ronate and the heattreatment was done at (900-1000 c) . The assurance of getting the glassy state through the XRD measure to the resulted samples was done . and the chemical composition of glass resulted by alkaline melting way was identified , then doing the chemical analyses needed to signify the percentage of oxides of the elements and in the second step of the worke , they have made tests on the resulted glass (its intensity, its resistance of acids and bases ). The decrease of intensity was noticed by the increase of silica concentration , sodium oxide and borates oxide , and it was noticed the increase of the resistance to the acids and alkalis by the increase of silica concentration and sodium oxide , but through adding the borates, the result was a glass less resistant to the acids and bases .
