FIELD: chemistry. ^ SUBSTANCE: invention relates to construction materials, specifically to a construction mixture and a method of making concrete from the said mixture and can be used in making concrete and reinforced concrete products. The construction mixture contains cement, sand, filler, complex additive and tempering liquid. The cement used is slag portland cement, the sand used is mine sand - iron ore tailings from Abagursky agglomerative-concentration plant, the filler used is crushed blast-furnace slag, the complex additive used is Relamix. Type 2, and the tempering liquid is freshly structured liquid in amount of up to free-running mass, with the following ratio of components: slag portland cement - 15-18; blast-furnace slag - 50-60; said mine sand - 21.9-34.7; Relamix. Type 2 - 0.1-0.3. The method of making concrete from the said construction mixture involves putting the tempered mixture into a mould, packing and hardening. The construction mixture is put into the mould. After 2.5-3 hours from the tempering moment, the mixture is further treated with structured water. ^ EFFECT: higher quality of concrete and shortening of its hardening period. ^ 2 cl, 2 tbl |
