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 ...
This makes it substantially important construction material in civil engineering projects.

· The gypsum and sandstone used for the tests are in strict accordance with the international rock mechanics test specifiion. Both ends of the gypsum and sandstone are carefully ground to make the upper and lower surfaces parallel as per the test requirements. The basic parameters of the samples are listed in table 1.
This rock form due to weathering actions such as rain, sun, air, frost etc. Due to Climactic changes this rock break into piece's. This piece's of rock carry by rain water into river. And due to striking of pieces of rock it convert into sand, silt etc.
Gypsum lath is similar to gypsumboard in that it consists of a core of set gypsum surfaced with paper. The paper for gypsumboard, however, is produced so that it is ready to receive paint or paper, while that for gypsum lath is specially designed or treated so that plaster will bond tightly to the paper.
· Rock Forming Minerals. 1. Feldpars: Feldspar is the most abundant minerals. There are two types. Orthoclase feldspars contain potassim (KalSi 3 O 8) and usually range from white to pink. Plagioclase feldspars contain sodium (KalSi 3 O 8 ), calcium (CaAl 2 Si 2 O8) or both, and range from white to gray to black,. Feldspars have moderate hardness.
Civil Engineering Dept., Faculty of Engineering, AlIsra University, Jordan, Email: orabialrawi ABSTRACT The influence of temperature, flow velocity, gypsum content, salinity of solvent and hole diameter on the amount and rate of dissolution of gypseous rock samples was investigated. The rock samples were obtained
