【 摘 要 】

The paper presents the results of studies on the replacement of a cement binder in a concrete mixture with fine blast-furnace granulated ground slag. This material has found its application in construction as an active mineral additive, improving the structure of concrete, and it also allows reducing the cost of concrete production. The results of the matching composition of concrete class B25 with a cement binder, as well as with the use of ground slag, are demonstrated. The information on the physico-mechanical characteristics recorded during the preparation of the concrete mix is also given. As a result of the control samples testing, it was revealed that the replacement of cement with slag in the range of up to 30 percent allows achieving the required parameters of compressive strength. This circumstance makes it possible to speak about the possibility of using blast-furnace granulated ground slag for building structures both in factory production and in the production of monolithic structures at the construction site.
