Trends and developments in green cement “A sustainable approach”
It is evident from the history of cement that it’s a vital construction material but its hazardous effects on environment cannot be ignored. Cement production causes serious environmental damages from its production to disposal which includes carbon dioxide emissions, noise/vibration pollution and damage to natural rocks (during extraction of raw materials from quarries). Cement is considered to be the third largest (man-made) source of greenhouse gas due to emission of carbon dioxide in atmosphere. The harmful effects of cement are encouraging the construction industry to use new cementitious materials without compromising cost and quality. Efforts are being made to develop supplementary cementitious materials using domestic, agricultural and industrial wastes and also recycled materials. This review study presents a concise review of current efforts for undermining production and use of cement. This paper will also highlight some important green alternatives for cement which include energy effective, low carbon production, no carbon cements and inorganic materials.
