Dolomite is a mineral that is composed of calcium magnesium carbonate (CaMg(CO 3) 2). It is formed from the alteration of limestone or lime mud. Dolomite is commonly found in sedimentary rocks and is often associated with limestone, calcite, and aragonite. Dolomite has a hardness of 3.5-4 on the Mohs scale and a specific gravity of 2.85-2.9.

The dolomite sample was placed between two bars with a length of 3190 mm made of C45 high-strength steel. The interaction process between all components was numerically defined using the penalty-based contact algorithm. Due to the use of lubricant in the actual tests, friction was neglected in finite element analysis (FEA).

Applications in Detail. Construction: Dolomite, in its crushed form, is used for producing concrete and cement. Its high hardness makes it a robust material for construction purposes. Agriculture: Farmers use dolomite for agricultural pH control. The chemical industry uses the mineral dolomite in making magnesium salts.

Deicers and Concrete. During the winter of 2002 and 2003, western New York experienced a significant increase in scaling and spalling concrete. As a large materials supplier located in Rochester, N.Y., the Dolomite Group knew it was producing products that met expected quality standards, but these products weren't meeting …

It was determined that linear shrinkage after 35 days for cement containing dolomite filler is lower than for pure Portland cement. The composition with 50% filler with a specific surface area of 639.9 m2/kg has the minimum shrinkage. In this case, the shrinkage index is 21% less than the pure cement.
