Composition of cement. Introduction Portland cement gets its strength from chemical reactions between the cement and water. The process is known as hydration.This is a complex process that is best understood by first understanding the chemical composition of cement.
estimated that cement production originates about 5% of global manmade CO 2 emissions [13]. The typical gaseous emissions to air from cement production include NOx, SOx, CO, CO 2, H 2 S, VOCs, dioxins, furans and particulate matters [14], [15], [16]. These major pollutants can be classified in two categories- gaseous and particulates.
cement industry has been using large quantities of waste fuels or biomass fuels, for more than 15 years. The production of cement involves the consumption of large quantities of raw materials, energy, and heat. Cement production also results in the release of a significant amount of solid waste materials and gaseous emissions.
Energy use – and in particular fuel use – is a major price factor in the production of cement. Because of this, companies in all three countries have invested in energy efficiency measures, such as converting wet kilns to dry kilns, or to adding precalciners and predryers to their cement production process, a more efficient process in terms of
