Dolomite is a double carbonate of calium and magnesium, CaCO 3, MgCO 3. It is of sedimentary origin and is supposed to have been formed due to chemical action of sea-water containing high percentage of magnesia, on limestone. Theoretically, dolomite contains: CaCO 3 - 54.35% MgCO 3 - 45.65% In other words, it contains: CaO - 30.4% …

Jun 01, 2018· The presence of dolomite renders limestone unsuitable for the production of clinker, as the dolomite will decompose in the rotary kiln to form periclase (MgO), which forms brucite (Mg(OH) 2) during the later stages of cement hydration. The formation of brucite from periclase is an expansive reaction and makes the cement unsound.

that the addition of dolomite in powder form to cement performs a comparable compressive strength to Portland-limestone cement [1,2]. Moreover, similar to limestone, dolomite may be involved in hydration of cement, resulting in the formation of carboaluminates and the stabilization of ettringite. Besides, Mg released from dolomite is considered ...

May 31, 2022· The Kona Dolomite is a sedimentary rock that was made when limestone turned into a different kind of rock. It's a dark gray to black rock, but when it's out in the air, it turns a unique yellowish-green color. It forms in places where volcanic activity buried limestone and heated it up. In this process, dolomite was made from the original ...

Dolomite lime is used for raising the pH of acidic soil. It is often used as an alternative to lime when the soil also needs a magnesium boost. The danger of using ordinary lime is that too much calcium in soil can prevent uptake of magnesium by plants. Using dolomite lime instead will add magnesium and calcium to soil in more equal amounts.
