FIELD: chemistry.
SUBSTANCE: invention relates to the industry of construction materials and particularly to making fine grained concrete which can be used in low-height construction. The crude mixture for making concrete contains the following, wt %: portland cement 22-24, flue ash 26-30, pumice ground until complete passage through sieve No008 44.7-51.1, superplasticiser S-3 0.9-1.3, with water-to-cement ratio of 0.4-0.45.
EFFECT: low cement consumption in the crude mixture for making concrete while preserving strength of the concrete.
