PROGNOSTIC MODELS FOR CREATING THE NEW COMPOSITE FIREPROOF CONCRETES AND MASSES FROM SECONDARY MINERAL RESOURCES

The idea of prognostic models is closely associated with the notions of predicting and modeling. To develop the prognostic models for creating new fireproof environmentally friendly concretes and concrete masses from secondary mineral resources (SMR), the existing and new theoretical and experimental investigations, the practical results obtained and modern technologies for mechanochemical treatment of the resources (both natural and the SMR) have been combined. The advantages of this approach make it possible to considerably reduce the number of the expensive experiments on the actual objects and to use simple enough mathematical models in a system of the so-called actual-model complex (AMC). As a result of the research on prognostic models, a block-Scheme for the automation of proportioning mixtures of fireproof concretes and masses from the SMR and a programme of the dependence of their properties on the mineral composition of the SMR as well as the conception for creating new composite fireproof concretes and masses from the SMR, using mechanochemistry, have been developed. The thermodynamic feasibility of producing not only bi-(C₂S; C₃A; MgSiO₃; 2Al₂O₃-2SiO₂ etc) but also multicomponent (C₄AlFe; MgFeSiO and others) combinations has been predicted.
