Abstract
Bases of manufacture of silicate materials of non-autoclave hardening are developed. The opportunity of realization of a complex of technological regimes on use of reserves of a structure of mineral substances in manufacture of silicate materials of non-autoclave hardening and wall's articles on their basis is theoretically proved and practically confirmed. With use of elements of experimentally-statistical modelling the analysis of influence of contents and hardening conditions on characteristics of structure, microstructure and property of silicate materials of non-autoclave hardening has been performed. The analysis of interrelation properties with structure’s parameter, content and technological regimes is necessary for regulation quality of the received composite material. Carrying out of the given researches with application of experimentally-statistical models is proved. The algorithm and strategy of the analysis of results of experiments is stated. The tactical line of structures optimization and technological regimes on experimentally-statistical models is effectively defined. Experimentally-statistical models allow to consider simultaneously significant number of factors in conditions of concrete manufacture. These models allow to spend the deep analysis of a concrete situation and to consider features of gears of hydration and structuration. The analysis algorithm of process of structuration at various stages of technology with use of experimentally-statistical modelling and methods of computer material science has been offered. This algorithm enables the following: a quantitative description of structure parameters at each stage of technology and an estimate of opportunities of their regulation; an analysis of change of interrelations between properties and characteristics of structure under influence of content and technological regimes; leading the search for optimum structures and technological regimes within the limits of the accepted approach.
