gypsum requirements in cement industry

FEATURE Gypsum The role of gypsum in cement

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. This paper discusses to begin with the role and

quality of gypsum for cement industry

Gypsum is called the retarding agent of cement which is mainly used for regulating the setting time of cement and is an indispensable component. Without gypsum, cement clinker can condense immediately by mixing with water and release heat.

What is the purpose of adding gypsum in cement?

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.

Gypsum Content an overview ScienceDirect Topics

One of the main mineral components in cement hydration is tricalcium silicate (C 3 S). Bentur (1976) reported that increasing gypsum content resulted in the acceleration of C 3 S reactions. At 3 and 7 days, a maximum compressive strength was achieved for mixes containing 2% gypsum.

Multi-functional polymers for Cement Lime

Gypsum binder used for gypsum board production is plaster, also known as stucco, with beta-calcium sulphate hemihydrate as the main gypsum phase. Normal plaster needs approx. 4 times the amount of water to flow than necessary for hydration. This excess water must be removed by heating and evaporation from the boards. The drying process has become the main cost-driver of production.

Determination of carbon and sulphur analysis in the

The sulphur concentration in cement is dominated by the gypsum content. This calcium sulphate is very strong so that it needs a very high temperature to crack it in a combustion analyser. Temperatures higher than 2000°C are needed to get the total sulphur out of the cement without using toxic accelerators.
