FIELD: construction.
SUBSTANCE: concrete mix includes portland cement, filler, tempering water and additive - complex solution with pH=4-5 with H4SiO4 sol base, besides, the specified complex solution is prepared at the following ratio of mixture components, wt %: microsilica 0.113-0.227, superplasticiser Relamix type 2 with pH=9±1 0.076-0.15, concentrated hydrochloric or acetic acid, or sulphuric acid 0.011-0.023, water 3.58-7.16 at the following ratio of concrete mix components, wt %: portland cement 22.63-22.68; filler 67.91-68.04; specified additive 3.78-7.56; tempering water 1.9-5.5.
EFFECT: higher strength of concrete during compression and reduced consumption of expensive additives of microsilica and superplasticiser.
