Environmental impact of concrete

The environmental impact of concrete, its manufacture and applications, are complexSome effects are harmful; others welcome Many depend on circumstanc A major component of concrete is cement, which has its own environmental and social impacts and contributes largely to those of concrete The cement industry is one of the primary producers of carbon dioxide, a potent greenhouse gas...

What makes the cement industry very polluting?

60% of CO2 released by a kiln is from the decompostion of the limestone, which is a raw material used in cement production And the rest 40% comes from the combustion of fuels which generate the high heat/temperature for the clinkering process to occur in the kiln...
