Some characteristics of heat-resisting concretes modified by SiO2 and TiO2 nanoparticles
Nanoparticles of SiO2 or TiO2 have been added in the preparation of heat-resisting concretes of two types. The major technical and chemical characteristics have been determined. Features have been found in some of the technological operations in making the concretes of both types, and also aspects of the physicomechanical properties. Higher chemical stability has been found for heat-resisting concrete containing TiO2 nanoparticles in an NaOH solution.
