Fine-Grained Concrete of Composite Binder

[摘要] The article is devoted to the application of industrial wastes for the production of high-quality concretes with specified characteristics. The composite binders with low water demand (BLW) have been developed. Their strength is approximately twice the strength of the initial cement, and dilute BLW with 50 - 70% of the ground slag or quartz sand in their composition provide the same strength as the original Portland cement. It was proved that the quartzite sand screening can be used as a filler in the preparation of fine-grained concretes.
