This paper presents a simple model for the study of the dissolution of calcite and precipitation of gypsum in acidic solutions. The numerical predictions of calcium and hydroxyl ion concentration have been used to develop approximate analytical expressions for the growth rate of calcium in solution, and the hydroxyl ions concentration.
The terms cement and concrete are used interchangeably, although cement is actually an ingredient of concrete. Gypsum is often added to cement and concrete to slow down the drying time. Cement dries quickly and retarding that process allows workers to pour .

Gypsum can also form translucent crystals and may be associated with calcite, but gypsum only has one very well developed cleavage plane, while calcite has three that form welldeveloped rhombs. Unlike calcite, gypsum does not react with dilute acid to form bubbles, although if the gypsum is crushed into a powder it may simply dissolve.
Nov 03, 2010· In toothpaste, calcite is used as a filler and mild abrasive since it is softer than the material your teeth are made of, fluorapatite. In cement the chemical properties of calcite, which is calcium carbonate, are utilized to create the chemical reaction that transforms powdered cement and water into hard concrete.
Gypsum board is the technical product name used by manufacturers for a specific board with a gypsum core and a paper facing and may be further described as follows: Regular Gypsum Board – a gypsum board with naturally occurring fire resistance from the gypsum in the core; or

Nov 04, 2011· The key difference between gypsum and limestone is that the calcium sulfate is the main constituent in gypsum whereas calcium carbonate is the main constituent of limestone.. Limestone and gypsum are minerals that form from calcium salts; limestone contains calcium carbonate while gypsum contains CaSO 4 ·2H 2 O. However, their properties and usages are different from each other.
Introduction. The overall process of dissolution of carbonate minerals and precipitation of gypsum is relevant in environmental settings, such as the treatment of acid mine drainage (AMD), geological CO 2 sequestration and monument preservation. The use of limestone (calcite) in the treatment of AMD with elevated concentrations of heavy metals and sulfate is common [1–5].
Gypsum is a common mineral, with thick and extensive evaporite beds in association with sedimentary rocks. Deposits are known to occur in strata from as far back as the Archaean eon. Gypsum is deposited from lake and sea water, as well as in hot springs, from volcanic vapors, and sulfate solutions in veins.
