Phosphogypsum refers to the calcium sulfate hydrate formed as a byproduct of the production of fertilizer from phosphate is mainly composed of gypsum (CaSO 4 ·2H 2 O). Although gypsum is a widely used material in the construction industry, phosphogypsum is usually not used, but is stored indefinitely because of its weak longrange storage is controversial.
Calcium carbonate and sulphuric acid are two separate chemical compounds. (Calcium carbonate is CaCO3 and sulphuric acid is H2SO4.) If these compounds are mixed together, a vigorous chemical reaction occurs forming calcium sulphate and water while...

In the case of ordinary Portland cement, sulfuric acid attack manifests itself by deposition of a white layer of gypsum crystals on the acidexposed surface of the specimen. In the case of geopolymer cement tested, unlike Portland cement, no gypsum deposition can be detected visually. During the course of corrosion, the
Of the total supply of crude gypsum, million tons, including 800,000 tons of byproduct gypsum, million tons was calcined for gypsum products, and million tons was used mainly as a cement retarder or as agricultural land plaster. The calcined gypsum was sold as prefabricated products or as industrial or building plaster.

Gypsum. Chemically known as "calcium sulfate dihydrate" (CaSO 4 ·2H 2 O), gypsum contains calcium, sulfur bound to oxygen, and water. The majority of gypsum (white rock) produced in North America is used to manufacture gypsum board, building plasters, and cement production.
Aug 07, 2010· sulfuric acid from gypsum CaSO4 Also, came up with an industrial process for producing sulfuric acid from common and inexpensive gypsum (CaSO4). An old chemistry book I had said that scientists couldn''t find a commercially viable process for turning this potential resource into the highly useful acid product.

However, betagypsum is a lowcost gypsum due to its simple manufacturing process and low energy requirements. Similar to cementbonded composites, gypsumbonded composites generally contain a high percentage of gypsum in the product. The gypsum matrix, therefore, participates substantially in the performance of the composite being manufactured.

Gypsum is also formed as a byproduct of sulfide oxidation, amongst others by pyrite oxidation, when the sulfuric acid generated reacts with calcium carbonate. Its presence indicates oxidizing conditions. Under reducing conditions, the sulfates it contains can be reduced back to sulfide by sulfatereducing bacteria.
