Aspects of application of industrial aluminosilicate wastes in production of zero-cement construction composites

Utilization of industrial wastes in great volume is one of the basic strategies of industrialized countries [1]. Such by-products of metallurgical industry as blast furnace slag are widely used in construction when production of cement-based materials. The studies related to synthesis of free-of-cement binders, using a blast furnace slag as a basic binding component are also carried out. However, significant variability in composition and properties as well as insufficient knowledge explains a limited application of blast furnace slag as independent binding component. That is also is relevant to alkali activated free-of-cement binders. In framework of this study the aspects of strength characteristics formation in alkali-activated binders based on blast furnace slag taking into account the parameters of alkaline activation and curing conditions. The concentration of alkaline agent was determined to be effects differently in the studied slags. Positive effect on structure and strength formation in the binder during thermal curing was observed.
