FIELD: construction materials.
SUBSTANCE: raw mix for the preparation of high-strength self-compacting concrete using man-made material, for the production of thin-walled tongue-and-groove blocks (Lego blocks) and products. High-strength self-compacting fine-grained concrete includes, wt.%: Portland cement - 23.82-29.8, finely ground scrap of heavy concrete - 10.2-13.06; additive micro-reinforcing cement stone - 4.46-8.84; microsilica CENTRILIT FUME S - 2.69; screening of quartzite sandstone crushing - 44.21; superplasticizer @MC-PowerFlow 3100 RU@ - 1.34; water - the rest.
EFFECT: expanding the range of tools for the development of compositions of high-strength self-compacting fine-grained concretes with increased strength characteristics, high density, low water absorption of concrete, low air shrinkage, low water-binding ratio and low consumption of Portland cement.
