Reduction of Greenhouse Gases Emission in the Cement Industry

Because of demanding to common procedure of cement in the civil and industrial works, different resolutions which can decrease amount of environmental destruction with this industry, must be examined. One of resolutions is using of the pozzolana cements. The pozzolana are silica and silicon alumina materials which cause improvement of cement properties with adding it to cement. In this article with doing of different trials on the Portland and pozzolana cement of western Azerbaijan in Iran their properties (amount of consumed energy and strength) have examined. These trials were carried out from ۲۰۰۶ and continued until ۲۰۰۸. Continuity of research is concentrated on the amount of diffusion harmful gases including both sort of cements. Results showed that with using pozzolana, diffusion of CO۲ is decreased within ۳.۵ - ۷% and this event causes decrease of cement environment destructive influences.
