IMPROVING TECHNOLOGICAL CEMENT QUALITY PARAMETERS

Abstract

Based on the compounds of the four –component CaO – BaO – Fe2O3 – SiO2 system, we developed for this purpose the technology for the production of special corrosion-resistant cements of a polyfunctional type that can be used for the production of extra strong radiation-protective and corrosion –resistant plugging cements. Calcium-barium ferrosilicate cement hydration processes were investigated and it was established that the main hydration products are barium hydrosilicates and calcium and barium hydroferrites of a different basicity that provide high strength characteristics for the cement stone.
