Cement history. Throughout history, cementing materials have played a vital role and were used widely in the ancient world. The Egyptians used calcined gypsum as a cement and the Greeks and Romans used lime made by heating limestone and added sand to make mortar, with coarser stones for concrete.
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.
2001. Use of synthetic gypsum as a raw material for wallboard plants increased in 2002. During 2002, the gypsum industry experienced several acquisitions, continued bankruptcy reorganization, opening of new plants, closing of older facilities, and expansion of production capacity at existing plants.
Use : As a bounding compound. Raw Materials : limestone, Sulphuric acid CaCO 3 + H 2 SO 4 = CaSO 4 +H 2 O Different form of synthetic or byproduct gypsum are now available for use and are being produced at economical rates which help the gypsum producers. In the business of making cement, gypsum costs usually very economical.

Synthetic gypsum, namely FGD (flue gas desulfurization) gypsum – a byproduct of coalfired energy production – is already widely accepted as a replacement for natural gypsum in many settings, including use as a soil amendment, in glass manufacturing, cement products, and more. This not only provides a readily available, costeffective ...
Most of the energy use and CO 2 emissions of the cement industry is linked to the production of clinker, which is the main component of cement and produced by sintering limestone and clay. Electricity needed for crushing and grinding raw materials, fuel, and the finished products represents another important energy demand.
FEECO has been providing the best in highquality, custom gypsum equipment and process solutions for decades. We frequently help our customers with pelletizing gypsum for use as a soil amendment, drying gypsum ore, processing FGD gypsum (synthetic gypsum), and more.
'Portland Cement' is the most common cement type and is composed of 95% clinker and 5% gypsum. The gypsum is ground together with the cement clinker to control the setting of cement and allow the mortars and concretes produced with the cement to be worked into .

The dryer will be used to dry flue gas desulphurisation (FGD) gypsum from a captive coalpower plant for use in cement plants. In the planned dryer plant the moisture of the FGD gypsum will be reduced to a residual moisture of <2%. Artificial gypsum from the dryer will be used at other cement .
Gypsum industry comprises companies that operate by manufacturing gypsum products; products such as wallboard, plaster, plasterboard, molding, ornamental moldings, statuary and architectural plasterwork. Gypsum product manufacturers may mine, quarry or purchase gypsum for use in the manufacture of their goods.
The dehydration of gypsum in the cement mill was simulated in the laboratory by grinding clinker with gypsum to form cement, and then dehydrating the gypsum by heating the cements for various periods.

The use of concrete in construction grew rapidly from 1850 onward, and was soon the dominant use for cements. Thus Portland cement began its predominant role. Isaac Charles Johnson further refined the production of mesoPortland cement (middle stage of development) and claimed he was the real father of Portland cement.
The news is relevant for the cement industry because both companies are prominent gypsum producers. They are leading gypsum wallboard producers, with assets around the world, including gypsum mines. Although their focus is on wallboard a significant proportion of raw gypsum ends up being used in cement production.
