STAR 3Micron
Contributes to the workability and durability of high strength concrete.
STAR 3Micron is an environmentally sustainable Class F ultrafine fly ash that provides a reactive surface area, generating higher early strength and lowering permeability. The size-classified ultrafine ash offers unique advantages for high-performance cementitious applications and increased durability for aggressive environments.
STAR 3Micron imparts many of the desirable hardened concrete traits associated with highly reactive pozzolans without increasing workability and placement demands. The ultrafine fly ash reduces water demand and superplasticizer demand compared with cement-only mixes. No special batching, transportation, or placement and finishing operations are required.
