COMPOSITE RAW MIX FOR MANUFACTURE OF HYDRAULIC PILES Russian patent published in 2022 - IPC C04B28/04 C04B18/08 C04B24/24 C04B111/20 

FIELD: building materials.

SUBSTANCE: solution relates to building materials and can be used for the manufacture of hydraulic piles. The composite raw mixture for the manufacture of hydraulic piles contains Portland cement, crushed stone, sand, fly ash, superplasticizer, water, and MasterGlenium ACE 430 was taken as a superplasticizer on a polycarboxylate ether base and additionally a viscosity modifier MasterMatrix 100 was introduced at the following ratio of components, wt.%: Portland cement 15.86-17.84; fly ash 1.984-3.96; sand 37.4-37.82; crushed stone 33.28-33.7; superplasticizer 0.14-0.16; a viscosity modifier 0.016-0.020; water 8.5-9.32.

EFFECT: increase in strength, water resistance, coefficient of expansion of coarse aggregate grains and coefficient of hydraulicity.
