| Title of the article | Effect of mineral additive based on ground blast furnace slag on the properties of concrete and concrete mixtures |
| Abstract. | Problem statement. The replacement of a part of the mineral binder with production waste is an urgent issue of construction materials science. The paper presents the studies of the effect of a mineral additive based on ground blast furnace slag on the properties of concrete and concrete mixtures. It is also known that mechanical activation affects the surface of the particles, thereby changing not only the chemical, but also the physical properties of the activated material. Therefore, the purpose of this study is to evaluate the effectiveness of a mineral additive based on ground blast furnace slag, including after mechanical activation, for the production of concrete and concrete mixtures. The objective of the study is to determine the effect of a mineral additive based on ground blast furnace slag and its mechanical activation on the mobility of concrete mixtures and the strength properties of concrete. Results. The main results of the study are that the introduction of a mineral additive based on ground blast furnace slag in the amount of 10-30% slightly increases the mobility of the concrete mixture and the strength of concrete. However, mechanical activation of the mineral additive makes it possible to increase the mobility of the concrete mixture from 4.5 to 17 cm while reducing the strength of concrete to 36% in comparison with the control composition. Conclusions. The significance of the results obtained for the construction industry consists in substantiating the possibility of replacing part of the cement with a mineral additive based on ground blast furnace slag for the manufacture of heavy concrete of medium strength. |
