Applied methods of estimation of refractoriness of constructions made from composites-reinforced polymer concretes

The refractoriness of chemically stable constructions on the basis of polymer concretes were investigated with the aim of development of the methods of estimation and improvement of refractoriness of the constructions made from reinforced polymer concrete according to their supporting power of normal section. As a result some elements of the theory of heat conduction were developed as well as the diagram of thermomechanical state of polymer concrete under compression with due regard for the heating temperature. The model of the loaded element resistance against the non-stationary thermal effect was also developed. The computer aglorithm and programme for the solution of the boundary-value problem of the heat conduction of a solid made from polymer concrete were developed and the methods of solution of the problem of refractoriness were elaborated. The functions of refractoriness and criterium of the limiting state by the supporting power were determined. The results obtained were introduced intopractice. They may be used in design and construction as well as in the educational processesAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
