A naturally occurring mineral consisting of calcium sulphate Gypsum is a flocculating agent for mushroom compost and is considered a conditioning agent Gypsum is used in compost to reduce its tendency to become greasy-a very undesirable condition
a common white or colorless mineral (hydrated calcium sulphate) used to make cements and plasters (especially plaster of Paris)
Represented by ( CaSO4,2H2O) is mixed with cement clinker during grinding Gypsum retards setting time of cement
Hydrated Calcium Sulphate Can form when limestone is attacked by sulphuric acid The resulting product is larger than its components so can be 'squirted' through pores in the rock under pressure, whilst in crystalline form
Gypsum is a soft white substance which looks like chalk and which is used to make plaster of Paris. Common sulfate mineral, hydrated calcium sulfate (CaSO42H2O), of great commercial importance. Deposits occur in many countries, but the U.S., Canada, France, Italy, and Britain are among the leading producers. Crude gypsum is used as a fluxing agent, soil conditioner, filler in paper and textiles, and retarder in portland cement. About three-fourths of the total production is calcined for use as plaster of paris and as building materials in plaster, board products, and tiles and blocks
A common soft evaporite mineral (alabaster, selenite, satin spar) used to make plaster of Paris
Mineral composed of calcium sulfate, typically produced in hyper-saline basins characterized by the evaporation of water that causes concentration of salts
A naturally-occurring, finely-grained solid consisting primarily of calcium sulfate (CaSO4) It also is chemically produced when making phosphate fertilizer and is known as phosphogypsum
A white mineral which is the main ingredient of plaster of Paris and gypsum board
