CONCRETE is hard, but not always hard enough. Some concrete floors wear out before their time.
To make them last longer, the marketplace offers a wide range of products, including dry-shake hardeners, sealers, and concrete admixtures.
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 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 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.
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. 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 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
Recommended uses
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, Ramp and Aprons
- Tunnels and Shafts • Skate Parks
- Storage Sheds and Tractor Garages
