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 %: cement 20-24; ash from burning brown or hard coal 74.2-78.4; capron fibre cut to 5-50 mm pieces 0.2-0.45; urea 0.1-0.15; superplasticiser S-3 1-1.5, with water to cement ratio of 0.45-0.6.
EFFECT: low consumption of cement while preserving strength.
