High-performance concrete KALCRET

Trowelable, sprayable or castable hard compound for plant components and pipe systems
Cyclone with KALCRET

KALCRET is a wear-resistant, high-performance concrete made of high-strength hard aggregates in an extremely strong cement matrix. The improved compound is matched to the specific requirements and provides maximum resistance to erosion and abrasion. 

KALCRET complies with strict international erosion resistance wear testing requirements according to ASTM-C704-15 and ASTM G65 as well as abrasion resistance wear testing requirements according to Böhme DIN 52108.

KALCRET combines excellent wear protection properties with ease of use. The specific advantage of all compound materials is their flexibility in practice. Large surfaces can be coated quickly and reliably to restore plant availability rapidly.

KALCRET is suitable for lining of plant components and piping systems, in power stations, in the steel and cement industries and in refuse burning facilities. Examples include pipe bends in coal dust piping, agitators for the removal of dust from blast furnace gases in steel works, and wind boxes and separator linings for the milling of cement.


  • Wear protection for application by trowel, pouring or spraying
  • Lining of large surfaces without joints
  • Easy lining of geometrically difficult surfaces
  • Variable layer thickness
  • Operational temperature max. 1200°C
  • Operational for full loading after only 24 hours
  • Easily combinable with all other materials
  • Repairs can be carried out easily


With KALCRET troweling compound, it is possible to protect horizontal, vertical, sloping, and curved surfaces. Safe overhead processing is also easily achievable.


The use of KALCRET casting compound is recommended when flat, nearly horizontal surfaces need to be protected against wear or when formwork can be used.


With KALCRET spraying compound, large surfaces can be applied in a short amount of time. Spraying can be done horizontally and vertically. Overhead processing is possible.
