Cement and its effect to the environment: A case study in ...

2009-4-27  The use of cement has long been the basis for development of society and for the welfare of the people for generations. Concrete, which is made from cement, has been the ultimate material for construction. Cement manufacturing process is intensive. Raw material extraction causes serious environmental problems by damaging the landscape and most of these raw materials become scarce. The cement industry recognizes its responsibility to manage the environmental impact, associated with the manufacturing of its product. Mainly, there are two types of cement production process; such as wet process and dry process. The preparation of cement includes mining, crushing, and grinding of raw materials, calcining the materials in rotary kiln, cooling, resultant clinker, mixing the clinker with gypsum and milling and bagging the finished cement. The cement production technologies in use cause extensive power consumption, gas emissions, noise pollution environmental heating and emissions of fuel (CO2, NOX SO2 and CO) from the kiln and precalciner. These are the major sources of environmental pollution in the cement
