Kryton Hard-Cem Concrete Hardening
HARD-CEM CONCRETE HARDENING
HARD-CEM CONCRETE HARDENING
Hard-Cem is an Integral Hardening Admixture used to increase Abrasion and Erosion resistance of concrete.
Hard-Cem is added to the concrete at the time of batching to increase the hardness of the concrete and extend concrete wear life.
It outperforms and overcomes deficiencies of labor intensive surface applied hardeners, and is used to enhance durability of both air-entrained and non-air-entrained concretes.
Since it is integral, Hard-Cem is compatible with horizontal, vertical or inclined concrete and shotcrete surfaces.

SAFETY
Read the Safety Data Sheet (SDS) for this product. For professional use only. Avoid contact with skin or eyes. Avoid breathing dust. Wear a dust mask, long sleeves, safety goggles and impervious gloves.
HOW IT WORKS
When added to concrete, Hard-Cem’s proprietary technology increases the hardness of the concrete paste and reduces fine and coarse aggregate exposure that creates degradation to concrete surfaces. Since it is integral it continues to offer surface wear resistance throughout its life. By increasing the abrasive-erosive service life of concrete, maintenance costs are reduced and replacement of the concrete is substantially deferred.
