AbstractAbout AuthorsReferences
At present the development of the production of autoclave silicate materials is restrained by high energy intensity and depletion of quartz sand reserves, which is a traditional raw material base, as well as by a limited opportunity to improve the performance characteristics of autoclave materials based on traditional raw materials. To increase the efficiency of production of both dense and cellular silicate materials, the possibility of using clay rocks of the incomplete stage of mineral formation has been proved. A specific feature of the phase formation in the calcareous-sandy-clay system has been established. It consists in accelerating the synthesis of the polymineral composition of neoplasms due to the rock-forming minerals of the rocks of the incomplete mineral formation stage, which optimizes the microstructure of the neoplasms. The rational kinetic parameters of the interaction in the calcareous-clay system and the magnitude of the maximum absorption of lime by clay minerals have been determined, which made it possible to develop a technique for calculating the raw mix for producing dense and cellular autoclave materials having high performance.
