Bangladesh''s cement sector is shaping up to be an interesting market from 2019. Gypsum demand is also burgeoning across the wider region, says Ramachandran. In Asia and South/East Africa, the over all demand for gypsum is expected to grow by 7 per cent CAGR from 2019.
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.

Because gypsum dissolves over time in water, gypsum is rarely found in the form of sand. However, the unique conditions of the White Sands National Park in the US state of New Mexico have created a 710 km 2 (270 sq mi) expanse of white gypsum sand, enough to supply the US construction industry with drywall for 1,000 years.
Product quality and compliance with dust emission limits are core requirements for dedusting in the cement, gypsum and lime industry. The choice of filter media is of paramount importance in cement kilns where there are high NOx levels due to high combustion temperatures.
Historically, Iran has exported around 10% of its total annual gypsum production, with the balance consumed by local cement, gypsum and construction industries. The gypsum production cost plays a major role in the Iranian gypsum industry and the profitability of gypsum production in Iran has decreased in recent years due to low FOB selling prices.

Domestic gypsum supplies are now limited, say industry executives, which is forcing Indian cement makers to look for overseas mine acquisitions or alternatively consider producing synthetic gypsum. Indian cement producers are particularly eyeing reserves located in Thailand, Oman, Iran and other countries in close proximity to India.
Gypsum, 2 to 3% is added to cement in powdered form to slow down the setting of cement. Thanks.
Key Words: anhydrite, gypsum, clinker, cement As it is well known, the workability property of cement solutions depends on reaction rate of C 3 A with water and to justify this, retarder raw materials are used. In cement industry, natural gypsum (CaSO 4 ·2H 2 O) is the most effective raw material for this purpose.

The terms cement and concrete are used interchangeably, although cement is actually an ingredient of concrete. Gypsum is often added to cement and concrete to slow down the drying time. Cement dries quickly and retarding that process allows workers to pour .
Cement, as a binding material, is a very important building material. Almost every construction work requires cement. Therefore, the composition of cement is a matter of great interest to engineers. For understanding cement composition, one must know the functionality of Cement ingredients.
Up to 200708, the Indian cement industry met their gypsum requirement predominantly from natural gypsum sources in Rajasthan and the byproduct gypsum from industrial sources. However, such sources for gypsum peaked and stagnated and the incremental requirement was met by imports, mainly from Thailand and Iran.
