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 can be used to enhance durability of both air-entrained and non-air-entrained concretes. Since it is integral, Hard-Cem can be used to harden horizontal, vertical or inclined concrete and shotcrete surfaces.
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.

Hard-Cem can be used in any Ready Mix, Shotcrete or Precast concrete to improve abrasion and erosion resistance, and extend the wear life of the concrete. It is typically used
