Hard-Cem is an integral hardener admixture used to increase the resistance of concrete to abrasion and erosion.
Hard-Cem is added to concrete during mixing to increase its hardness and extend its useful life. Overcomes the shortcomings of labor-intensive surface-applied hardeners. It also improves the durability of concretes with and without air inclusion. Since it is integral, it can be used in horizontal, vertical, inclined and cast concrete.
When added to concrete, Hard-Cem technology increases the hardness of the concrete paste and reduces the exposure of coarse and fine aggregates that cause degradation of the concrete surface. Since it is integral, it provides resistance to surface wear throughout its useful life. By increasing the service life against concrete abrasion and erosion, maintenance costs are reduced and concrete replacement is substantially delayed.
* compared to surface hardeners applied by spraying
Hard-Cem can be used in any ready-mix, shot, or precast concrete to increase resistance to abrasion and erosion wear and extend the life of concrete. It is typically used in the construction of:
