Abstract

The work is devoted to the designing of composite binders with the application of clinker, blast-furnace granulated slags and admixtures (CSCB), and the subsequent producing of efficient fine-grained paving flag concretes on its base. Due to the complexity of the binders’ formulas it will be possible not only to reduce the amount of clinker in the mixture, but to regulate the structure formation processes efficiently, providing the high quality of the produced concretes and products on their base. The article analyzes the influence of mineral admixture on structure formation processes and structural optimization of cement stone. There are obtained functions of the ultimate compression strength of a composite binder with mineral admixture and without it. Within this work there was carried out the research of the influence of the amount of blast-furnace granulated slag and admixture at producing CSCB on the activity of binders. There are developed the formulas of composite binders on the base of blast-furnace granulated slags, which allows reducing the consumption of clinker to 70% while providing the activity of binder within the range, required for producing paving flags.
