METHOD OF MANUFACTURING LIMESTONE WALLING CONSTRUCTION MATERIALS Russian patent published in 2018 - IPC C04B14/28 C04B20/04 C04B28/10 C04B40/02 C04B111/20 

FIELD: construction.

SUBSTANCE: technical solution relates to production of construction materials, namely to methods of limestone construction materials production, and can be used for production of walling materials. In the method for manufacturing limestone walling construction materials, including moistening and pressing limestone products, carbonization in a gaseous medium, molding mixture before the wetting is decarbonized by mechanical activation to a content of 0.2-2.5% calcium oxide, and carbonization is carried out in a gas medium containing 30-50% of carbon dioxide.

EFFECT: technical result is an increase in physical and mechanical characteristics of products, simplification of the method, decrease in energy intensity of the technology, increase in the volume of limestone to be processed.
