【 摘 要 】

Analysis of data from studies of aluminum silicate binder-based construction composites allowed giving theoretical justification and then experimentally confirming a possibility to control synthesis of new growth to obtain composites with predefined characteristics by means of using shales of incomplete clay synthesis of various genesis. Employing aluminosilicate rocks of incomplete clay synthesis, which contain thermodynamically-unstable compounds make it possible to shift from traditional raw materials to production of composite materials on the basis of natural polyfunctional raw material, thus allowing to accelerate synthesis of new growth, change its morphology, optimize microstructure of binding materials and as a result, to improve performance properties of final products. Improvement of performance properties of silicate materials and reduction of their energy content are provided by producing hydrogarnets and other CaO-Al2O3-SiO2-H2O compounds in the binding material under condition of hydrothermal treatment without additional pressure.
