#0183;#32;India''s cement production capacity stood at around 502 million tonnes per year (mtpa) in 2018 and is expected to reach 550 mtpa by 2025. Typically, manufacturing cement uses 2 to 4 per cent gypsum per tonne of cement. Thus the country requires importing substantial gypsum to cater to the requirements of cement industry.
G. Habert, in Ecoefficient Construction and Building Materials, 2014. Introduction. Cement production has undergone tremendous developments since its beginnings some 2,000 years ago. While the use of cement in concrete has a very long history (Malinowsky, 1991), the industrial production of cements started in the middle of the 19 th century, first with shaft kilns, which were later
Gypsum is a mineral and is hydrated calcium sulfate in chemical form. Gypsum plays a very important role in controlling the rate of hardening of the cement. During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process.
#0183;#32;Typically, manufacturing cement uses 2 to 4 per cent gypsum per tonne of cement. Thus the country requires importing substantial gypsum to cater to the requirements of cement industry. This has made the cement industry to look at the usage of different varieties of gypsum such as by product/chemical/synthetic.
