AbstractAbout AuthorsReferences
The disposal of waste from blast furnace steelmaking has been and remains an urgent problem. There is a possibility of using this type of waste when producing concretes for industrial and civil construction in order to save the initial components. The results of studies of a slag-alkaline binder and concrete based on it using ground blast furnace slag and experimental data on the development of a binder on different types of slag are presented. Experimental experiences were carried out at different densities of the alkaline solution. As an alkaline component, a soda ash fusion cake is used. Recommendations for the preparation of an alkaline solution are presented. The properties of the slag-alkaline binder, such as the setting time and strength, are considered. The properties of concrete based on this type of binder, such as mobility, density of the concrete mixture and strength, water resistance of concrete, are studied. In the course of the conducted studies, the optimal compositions of the binder and slag-alkaline concrete, strength class B20 and water resistance class W6 were selected. The results of the research can be used in the production of building structures for industrial and civil construction, as well as for further research and modification of the composition.
