Limestone Flour

Fine calcium carbonate limestone powder with about 90% passing a 100-mesh screen, this product has multiple uses. Limestone flour is used as an additive for asphalt applications and concrete products, as well as a calcium mineral supplement for animal feed products. Limestone flour reduces the cost and increases the durability of asphalt shingles and asphalt road mixes by displacing expensive asphalt with lower-cost calcium carbonate. In concrete applications, limestone flour increases the strength and improves the workability of concrete by acting as a high-quality paste extender. This displaces the higher cost of cement, and increases the total aggregate content of the concrete mix. The use of calcium carbonate in concrete reduces greenhouse gas production by reducing cement requirements.
