Dolomite powder, derived from the mineral dolomite (calcium magnesium carbonate), is increasingly used as a supplementary cementitious material (SCM) in concrete production. Its incorporation into cement and concrete enhances workability, durability, and performance characteristics, especially under severe environmental conditions such as extreme temperatures, chemical exposure, and moisture infiltration. Understanding the role of dolomite powder in concrete is essential for optimizing its formulation to withstand these harsh environments effectively.
