FIELD: chemistry. ^ SUBSTANCE: invention relates to concrete mixture composition, and can be used in the industry of construction materials and in making concrete objects and monolithic construction. The concrete mixture, obtained by mixing cement, sand and clay slurry in water, is treated with ultrasound with frequency of 110 kHz for 14 hours. Cement and sand are then added to the mixture in the following ratio of components, wt %: cement 18 to 29, sand 58 to 72, clay 0.4 to 0.7, water - the rest. ^ EFFECT: increased time-yield of concrete. ^ 1 tbl, 3 ex |
