METHOD OF PRODUCTION OF CURED PRODUCTS OF HYDRAULIC COMPOSITION Russian patent published in 2016 - IPC C04B28/02 C04B24/02 C04B22/08 C04B103/24 

Abstract RU 2600803 C2

FIELD: technological processes.

SUBSTANCE: this invention discloses a method of production of cured products of hydraulic composition obtained by mixing glycerine, cement and water, where hydraulic composition contains sulphate-ion, wherein this method includes stage 1 producing hydraulic composition, so that the molar ratio of sulphate-ion to glycerine, sulphate-ion/glycerine is from 5.0 to 20, and content of sulphate-ion ranges from 3.0 to 15 weight parts at 100 weight parts of cement; and step 2 holding and hardening of the hydraulic composition obtained at step 1. Invention also relates to hydraulic composition and to its use for early strength increasing. Invention is developed in subclaims of formula of invention.

EFFECT: increased early strength.
