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 22-25; ash from burning brown or hard coal 72.5-75.5; capron fibre cut to 5-50 mm pieces 1-1.5; superplasticiser S-3 1-1.5, with water to cement ratio of 0.8-0.9.
EFFECT: low consumption of cement while preserving strength of the obtained concrete.
