Fine-grained Fiber Concrete on Mechanoactivated Portlandcement
This article is devoted to the study of the mechanical properties of fine-grained concrete used for flooring in industrial and civil buildings. Characterized by the wellknown advantages (unlimited raw material base, manufacturability, high homogeneity), fine-grained concrete requires an increased consumption of cement to achieve the necessary mechanical characteristics - compressive strength, abrasion, impact resistance. An alternative to the known technological method is proposed an intensive separate technology (IST) for preparing fine-grained concrete mixtures using a high-speed mixer-activator in the presence of hydrophobized basalt fiber and a polycarboxylate superplasticizer Relaxol-Super PC. The use of IST leads to an increase in the strength of fine-grained concrete in compression by 1.9 times, impact resistance by a factor of 2, and a decrease in abrasion by 40 . 50% in comparison with the control. The relevance of using the technology of monolithic floors for industrial and civil construction is due to a wide range of varieties of Portland cement, the grain composition of aggregates, as well as the simplicity of the technology for preparing a fine-grained concrete mixture.
