FIBER CEMENT PRODUCTS FOR FLOORING AND THEIR PRODUCTION METHODS Russian patent published in 2021 - IPC C04B28/02 C04B14/06 C04B40/02 

FIELD: building materials.

SUBSTANCE: present invention relates to fiber cement products for flooring, additionally relates to methods for the production of such fiber cement products for flooring. A fiber cement product for flooring at least contains cement and fibers, wherein the specified fiber cement product for flooring contains amorphous silica in amount from about 2 wt. % to about 7 wt. % per the total dry weight of a fiber cement composition of the specified fiber cement product for flooring, while the specified fibers at least include synthetic fibers, and the specified product contains limestone in amount from about 5 wt. % to 35 wt. % per the total dry weight of the fiber cement composition of the specified fiber cement product for flooring. A method for the production of a fiber cement product for flooring at least includes stages of: (i) providing a fiber cement solution containing at least fibers, cement, water and from 2 wt. % to about 7 wt. % of amorphous silica and from about 5 wt. % to 35 wt. % of limestone per the total weight of solid particles in the specified solution, and the specified fibers at least include synthetic fibers; (ii) manufacturing the fiber cement product for flooring using a fiber cement production method; (iii) ensuring the curing of the fiber cement product for flooring.

EFFECT: technical result is an increase in the mechanical strength of fiber cement products.
