Mineral Powders for the Construction Industry

The construction industry is one of the largest volume consumers of mineral powders in India. At Ridhi Sidhi Microns, we supply construction-grade calcite powder, dolomite powder, and soapstone powder that meet the demanding requirements of this rapidly growing sector. Calcite powder (calcium carbonate) is the backbone mineral filler in construction chemicals, prominently in wall putty. Formulations typically contain 60–75% calcium carbonate. Our construction-grade calcite with whiteness of 93–96% provides the bright white colour and smooth texture demanded by manufacturers. In tile adhesives and grout formulations, calcite powder serves as the primary filler providing body, workability, and compressive strength. Dolomite powder plays an important role in cement manufacturing, providing both CaO and MgO to the clinker, which improves long-term strength development and durability. Soapstone powder finds application in specialized construction products including refractory mortars and fireproofing compounds where heat resistance is required.
