Modified Fine-Grained Concretes from High-Filled Self-Compacting Mixtures Containing Fine Natural Quartz Sand

The results of the study of water demand of fine natural quartz sands and physical and mechanical properties of self-compacting fine-grained concretes with the use of carbonate filler-microcalcite are given. The compositions of modified fine-grained concretes of compressive strength class C20÷C90 from self-compacting mixtures of workability class SF1 are developed.
