In a method of making a gypsum slurry, a polycarboxylate dispersant, a modifier and a hydraulic material comprising stucco are selected for use in the slurry. These components are then combined with water to form a slurry, where the modifier is added to the slurry prior to formation of a slurry phase by the water, the stucco and the dispersant.
· The preparation of surface and application of gypsum plaster should be apt to prevent cracks and peel offs. Storage of Gypsum. The surfaces exposed to moisture reduces the setting time and strength of gypsum plaster. So, gypsum bags have to be stored on elevated as well as a dry platform made of timber, brick or concrete. The shelf life of gypsum plaster is

· Gypsum (CaSO 2 O) Gypsum beds were formed due to the evaporation of water from the massive prehistoric sea basins. When water evaporates, the minerals present in it become concentrated, and crystallise. Properties of Gypsum · Gypsum is a soft mineral, which is moderately soluble in water. The solubility of this mineral in water is affected by temperature. Unlike other salts, gypsum becomes less soluble in water as the temperature increases. This is known as retrograde solubility,
