Hard-Cem is an integral hardening admixture used to increase Abrasion and Erosion resistance of concrete used in industrial or commercial structures.

Hard-Cem is added to the concrete at the time of batching to increase the strength and durability of the concrete and extends the surface wear resistance throughout the life of concrete. It outperforms and overcomes deficiencies of labour-intensive surface-applied hardeners, and can be used to enhance durability of both air-entrained and non-air-entrained concretes.

Since it is an integral hardening admixture, Hard-Cem can be used to harden horizontal, vertical or inclined concrete and shotcrete surfaces.

How it works

When added to concrete, Hard-Cem’s patented technology increases the strength of the concrete paste and reduces fine and coarse aggregate exposure that creates degradation to concrete surfaces. By increasing the abrasive-erosive service life of concrete, maintenance costs are reduced and the surface wear life of the concrete is substantially extended.

Features and Benefits

  • Extends concrete wear life up to 6 times under harsh conditions
  • Easy to use and easily added to the concrete
  • *compared to surface applied (dry shake) hardeners
  • Lowers installation costs*
  • Expedites construction schedules*
  • Reduces maintenance costs and improves concrete sustainability
  • Improved work site safety and conditions (Hard-Cem is dust free)*
  • Improved quality control*
  • Hard-Cem is the only hardener that can be used on air-entrained concrete*
  • No side effects on concrete water demand, workability, set time, strength development or shrinkage
  • Full depth concrete hardening*
  • Can be used in horizontal, vertical or inclined concrete

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

  • Manufacturing and Distribution Warehouse Floors
  • Service and Repair Bays
  • Highway Pavements and Intersections
  • Bridge Decks
  • Parking Structures, Ramps and Aprons
  • Tunnels and Shafts
  • Utility and Maintenance Buildings
  • Storage Sheds and Tractor Garages

Dosage Dosage is 40 kg/m³, displacing approximately 30 kg/m³ of conventional sand in the original concrete mix to maintain design yield

Packaging Hard-Cem is available in 20 kg mixer ready bags, 1,600 kg super bags and bulk pneumatic
