ASTM Aggregates

ASTM 6M, fine aggregate and ASTM#67 aggregate are mechanically crushed limestone that are particularly useful in concrete production due to the carefully engineered size distributions, and particle shape which provides high strength and increased bonding.


ConCarb™ is a de-dusted mineral additive designed specifically for concrete and concrete ready-mix products to improve workability, fluidity, green strength, particle packing and more. It enhances savings through cementious content reduction, reduces segregation and abrasion, and improves fire resistance compared to fly ash.
