More Information
Summary:The invention concerns a gypsum-free solid mixture on a base of ground clinker, which is used in construction in special applications requiring short and long-term rigidity. The mixture contains Portland or white cement clinker on a medium surface of 300 to 700 m /kg, a grinding additive, sulphonated polyelectrolyte, alkaline metal salt, filler, very fine amorphous SiO2, mixing water and a hardening regulator. The essence is that the filler contains 96 % by weight particles with grain size of 0.5 to 22 mm, whereas the number of shares of grain with diameter less than 0.5 mm and larger than 22 mm is 4 % by weight of the filler.
