Technical datasheet

The CFC plants manufacture CFC dry mixes for preparation of cellular concretes and other special application concretes with volume weights from 300 kg/m3 to 1800 kg/m3 and compressive strengths from 1 МРа to 40 МРа. Higher strengths are also achievable.

Below is the technical data of several CFC products with different volume weights. The expanding ability shows how many cubic meters are produced from 1 MT of the corresponding CFC dry mix.
