The average thickness of the layer is 30 to 40 m in these areas, amounting about 350 billion tones of .

Low Cement Castable Refractories. Low Cement castables are classified as castables with less than % 1% Lime (CaO). Designed for multiple appliions and multiple installation methods. Low cement castables are commonly utilized in the steel, aluminum, minerals processing, petrochemical industries, and .

Dolomite, also known as "dolostone" and "dolomite rock," is a sedimentary rock composed primarily of the mineral dolomite, CaMg (CO 3) 2. Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesiumrich groundwater. Dolomite and limestone are very similar rocks.

Cement and additive if mixed with water results in a cement hydration process followed by a cement setting process. The definition of cement hydration process itself can be described as a chemical reaction between solids and liquids, in which mixtures eventually sets. On cement suspension, the hydration process happens between clinker, calcium sulfate and water, which causes the cement .

According to the results of the experiments, the samples with the multifunctional additive "D5" showed the best characteristics of concrete, and the samples with the dolomite flour additive were the cheapest. As a result of the experimental analysis, the effects of three additives on the strength characteristics of concrete and water resistance were determined. Cemplast and D5 additives are highly effective .
