The building gypsum is white and has a density of to / cm 3 and a bulk density of 800 to 1000kg / m 3.. As per GB977688 building gypsum can be classified into highclass, firstclass and acceptable grades in light of strength, fineness and setting time (see the below table) Among them, bending strength and compressive strength are measured by letting samples contact with water for 2 ...
In this study, the effects of soaking time and confining water pressure on the compressive and flexural strengths of rock due to the dissolution of gypsum content in rock samples with 96% gypsum (CaSO 4 ·2H 2 O) content collected from northern Iraq (Kurdistan Region) were investigated. Experiments on compressive strength and flexural strength were performed on gypsum rock samples in normal ...

Calcium sulfate, commonly known as natural gypsum, is found in nature in different forms, mainly as the dihydrate (CaSO4 · 2H2O) and anhydrite (CaSO4). They are products of partial or total evaporation of inland seas and lakes. Both the dihydrate and the anhydrite occur in nature in a variety of forms. The origin of gypsum, its genesis, varieties and properties are discussed, and the focus is ...
