MODIFIER OF STRUCTURE AND PROPERTIES OF CEMENT STONE Russian patent published in 2022 - IPC C04B28/04 C04B22/08 

FIELD: building materials.

SUBSTANCE: invention relates to the building materials industry; it can be used for the manufacture of materials and products of concrete in civilian and industrial construction, including with the use of nano-technologies. The modifier includes Portland cement, water, and an additive – hydrosol of calcium chloride salt CaCl₂. The additive – hydrosol of calcium chloride salt CaCl₂, introduced in a composition of Portland cement, is prepared by hydrolysis of calcium chloride salt CaCl₂ in the form of 2% concentration solution, wherein the dosage of the solution of calcium chloride salt CaCl₂ ranges from 0.2 to 1% of the cement weight, while a flow rate of dry salt is from 0.004 to 0.02% of the cement weight.

EFFECT: increase in compressive strength of cement stone, reduction in a flow rate of a modifier of a structure and properties of cement stone, reduction in cost price of concrete materials and products based on modified cement, easier and more available preparation of the modifier of a structure and properties of cement stone.
