Ivashchenko M. Cements based on the compositions of BaO - Al2O3 - Fе2O3 system for the protection from electromagnetic radiation

Object - the peculiarities of the processes of binding protective composition formations from electromagnetic radiation; purpose - the creation of new efficient construction materials with protective features from electromagnetic radiation on the basis of ВаО - Аl2О3 - Fе2О3 system compositions; methods - thermodynamical, X-ray phase, thermal, IR spectroscopy, electronic microscopy, physico-chemical; novelty - the possibility of obtaining special binding materials with a complex of pre-set characteristics based on hexaferrite and barium monoaluminate in BaO - Al2O3 - Fе2O3 system has been theoretically grounded; the regularities of high-temperature processes in the system have been determined; kinetic regularities of solid-phase processes passing have been determined; the main products of barium containing cement solidification have been determined; results - barium containing cement and based on it concrete for the protection from electromagnetic radiation have been obtained; sphere of application - new construction material for the construction and reconstruction buildings and structures; in the educational process.
