CAS: 7778-18-9
Calcium Sulfate Anhydrite Super (CaSO₄) is an extraordinarily specialized chemical compound employed primarily in the construction and other specialized trades. As an anhydrous form, its distinct quality cannot be compared with similar products, for it remains entirely water-free in structure, rendering it absolutely dry and completely concentrated. It appears as a fine, white powder and is well known to impart strength, durability, and rapid setting time to the materials it is added to. Traditionally, its use in the construction of plasters dates back to antiquity, and it remains a prime ingredient in modern high-performance materials.
One of its distinctive features is the property of Calcium Sulfate Anhydrite Super to impart the property of acceleration of curing to binders like plaster without prescribed dry times; production within a short time frame may be considered expedient for efficiency on construction works.
