Bykanov S. Special cements on the base of BaO-Al2O3-Fe2O3 system compounds

The special cements. The radiation-resistant cements and their concretes obtaining on the protection from the simultaneous influence of radiation and temperatures to 1300C aimed. The investigations were carried out by means of the physico-chemical analysis methods complex. By the temperatures 1200 and 1300C the system BaO-Al2O3-Fe2O3 triangulation has been completed. The protective high-strength (40-70MPa) cements on the base of BaO-Al2O3-Fe2O3 system compounds technology was elaborated. The phase-forming and hydration processes features of cements obtained were defined. The protective concretes with the different aggregates have been obtained. The tests were carried out. Application: nuclear power plants, nuclear physics.
