CONCRETE MIXTURE Russian patent published in 2014 - IPC C04B28/04 C04B24/24 C04B111/20 C04B103/32 

FIELD: chemistry.

SUBSTANCE: concrete mixture includes Portland cement, crushed granite, quartz sand, a microfiller, a superplasticiser based on polycarboxylates and water. Additionally into the mixture introduced is TTP fly ash, as the microfiller used is ground limestone MP-1, and as the superplasticiser, based on polycarboxylates MC-RowerFlow 2695, with the following component ratio, wt %: Portland cement 8-10, ground limestone MP-16-8, TPP fly ash 3-6, quartz sand with the coarseness module Mc 1.9 30-40, crushed granite of fraction 3-10 mm 15-18, crushed granite of fraction 5-20 mm 14-16, the superplasticiser based on polycarboxylates MC-RowerFlow 2695 0.0015-0.003, water - the remaining part.

EFFECT: increase of concrete quality due to increased fluidity of the concrete mixture and its self-compaction.
