Use of Ground Granulated Blast Furnace Slag in Cement Binder

The article presents the results of studies of cement binder with the addition of fine ground granulated blast furnace slag and concretes on its basis. This material finds its use in construction as an active mineral additive that improves the structure of concrete, and also allows you to reduce the cost of its production. The results of the selection of the composition of concrete of class B25, both on cement binder and with the use of ground slag are presented. Physical and mechanical characteristics of concrete mixture and concrete are given. As a result of tests of control samples it has been revealed, that the addition of slag in the interval up to 30% allows to reach the required indicators of the limit of strength in compression. The kinetics of gain of strength of concrete shows, that at the initial stage of the introduction of slag in cement reduces speed of gain of strength (1–7 days), but further, by the vintage age of 28 days speed of gain of strength of samples without addition and with the addition of slag in cement in the range 10–50% gradually are leveled. It should be noted that at the age of 56 and 90 days the control specimens of all the series show the results corresponding to the vintage strength of the respective series. This circumstance allows to judge about the possibility of using ground granulated blast-furnace slag in concrete in the production of building structures both in the factory and in the production of monolithic works at the construction site.
