Con-Fume® silica fume is a pozzolanic material used to produce high performance concrete or mortar possessing increased strength, impermeability and durability.
As a supplementary cementing material, Con-Fume meets or exceeds all current ASTM, CSA, and AASHTO specifications for silica fume.
Admixture for Abrasion and Erosion Resistance
Unlike post-applied surface treatments that delaminate over time, or high-strength concrete that’s prone to curling and cracking, Hard-Cem integral admixture significantly reduces replacement and repair requirements and more than doubles the concrete’s wear life — lowering its embodied carbon footprint over its lifetime.
