A review of cement life cycle evaluation studies in Iran

Cement industry is one of the important consumers of energy in the industrial sector. So that 4 gigajoules of energy is used to produce cement mortar. Due to the production and consumption of cement, this industry causes air pollution both through the production process and energy consumption (thermal and electrical), but today there is growing concern about the impact of man-made carbon dioxide emissions on global warming. Since the cement industry is the largest emitter of carbon dioxide in the industrial sector, so the study to reduce the environmental effects of cement is very important. This article provides an overview of research into the evaluation of cement life cycle. In general, the results of this review show that one of the ways to reduce environmental impact is to evaluate the life cycle of cement, and according to the results of improving mixed cements, it has more potential to reduce global warming than ordinary Portland cement and by reducing demand. Clinker production (through replacement), in contrast, also reduces the environmental impact of the final cement product.
