environmental impacts of cement production
the production of cement involves the consumption of large quantities of materials energy and heat. cement production also results in the release of a significant amount of solid waste materials and gaseous emissions. the manufacturing process is very complex involving a large number of materials
geology (raw materials) the fundamental chemical compounds to produce cement clinker are: lime (cao) silica (sio2) alumina (al2o3) iron oxide (fe2o3) (macfadyen 2006) (hoffman 2006) fly ash: by-product of burning finely grounded coal either for industrial application or in the production of electricity materials used in the production of
