Take it easy! Easy dry (ED) refractory concrete technology

The new Easy Dry (ED) refractory concretes have been developed and tested successfully.

The results in everyday use are convincing:
  • Suitable for all static areas of the cement clinker production line, including kiln inlet and outlet

  • Applicable with all installation procedures

  • Meeting the demands for fast heat-up and re-commissioning

  • Significant energy savings

  • Simple storage and easy handling‎


Combination of four – the CF family

Highly flexible and universally applicable refractory bricks: Our sustainable concept meets your demands – today and tomorrow.
When considering the overall economics of operating sequences, the quality of the refractory lining in a rotary cement kiln is gaining continuously in importance.

In this respect, Refratechnik has been providing important impulses for many years.

The CF family is a holistic range of perfectly matched products based on a patented elastification method – pleonastic spinel (fMA spinel).

Designed for optimum mutual matching, to meet today’s and future loads, environmentally compatible, and convincingly budget friendly.

Expect the best:
For us, quality and service go hand in hand.

Our comprehensive range of refractory products confirms that we understand the needs of the global cement industry.

The Mixcrete concept

The Mixcrete concept offers a wide, flexible and adapted application spectrum, also regarding graded alkali resistance and stress-reduced performance characteristics in zones subjected to higher thermomechanical stresses. The concept also offers flexible combination possibilities for low-cement refractory cements.

Mixing of standard low-cement types permits a more uniform product range to be held in stock. Consequently, a reduced number of products results in simpler storage, shorter storage times, and reduced storage costs. By means of individual use or bagwise mixing of up to six Mixcrete products or five Mixcrete combinations, both the normal and the highly stressed zones of a cement plant can be covered – from the cyclone stages up to the breaker in the cooler.

Depending on the recommended mixing ratios (3:1, 2:1, and 1:1), the flexibly applicable installation concept permits graded SiC contents of about 12...25 % by weight, so that particularly under the aspects of alkali resistance, higher thermal loading, reduced stress susceptibility, and lower expansion tendency, it is possible to obtain specific product properties locally and at any time, which are matched to the respective zone.
