The meaning of the name Anhydrite is "without water.". It is because this crystal is a mineral that belongs to a Sulfate group, linked to Gypsum, and forms as a result of its dehydration. These gemstones have a faint to mediumgray color yet seem colorless or bluish. Anhydrite also has a tabular shape with a flat, long form and a granular ...

Abstract. Aluminophosphate cement () is a new type of hydraulic cementitious material with many potential functions. Microscopic analysis techniques were used to study the effect of anhydrite on the performance and hydration process of under standard curing conditions. The results show that adding an appropriate amount of anhydrite ...

"Anhydrite contains calcium and sulphur important nutrients for crops," says Stéphane, a scientist in our Aluminium team. "It also helps improve soil texture and has no impact on pH levels, which all creates the right conditions for growing certain crops like potatoes, wheat, barley and now blueberries too."

Causes of Anhydrite/Gypsum Contamination. Calcium sulfate causes aggregation and flocculation of a fresh water mud, resulting in thickening. The calcium sulfate causes an increase in apparent viscosity, yield point (check also Yield Point In Drilling Mud), gel strength and filtrate. The partially soluble calcium sulfate increases the hardness and sulfate content of the filtrate.

The occurrence of anhydrite (Fig. ), anhydrous calcium sulphate CaSO 4, is rather rare. Anhydrite usually forms underlays in gypsum deposits. Anhydrite has a dense crystal structure because of the absence of crystallised water (Table ), which causes a higher value of mechanical properties. Download : Download fullsize image; Fig.

Cements with anhydrite set faster than those with gypsum (Fig. 4), and both present an optimum but at different % SO 3 content. In Fig. 5, it is evident that the addition of anhydrite accelerates the setting of faster setting of anhydrite is caused by the increasing amount of CaSO 4 in the admixture (Fig. 6).As anhydrite content increases by 1%, the initial setting time decreases by ...

fication of the amounts of anhydrite present (~3 × 108 kg; Humphris et al., 1995). Anhydrite was recovered from 3 of the 5 areas drilled (TAG1, 2, and 5; Fig. 1) throughout the range of depths drilled (up to 125 meters below seafloor (mbsf)). In all three areas, the downcore trends in anhydrite occurrence and style of mineralization are similar
