Complex modification of concrete composites

Objective. The aim of the study is to study the mechanism of chemical interactions with subsequent formation of new formations in the structure of concrete stone; undisclosed possibilities of modifying the matrix system with organic and mineral additives; development of filled highly active binders; use of enriched fillers of high quality; a combination of concrete, reinforcement and dispersed reinforcement, contributing to the evolution of the development of modern concrete science. Method. Research is carried out in accordance with regulatory documents GOST 12730.3–2020 Concrete. Methods for determining water absorption; GOST 10180-2012 Concrete. Methods for determining hardness using control samples; GOST 12730.1-78 Concrete. Methods for determining definition. Result. The complex use of organic and mineral additives was studied, which contributed to the accelerated formation of the structure and strength of the stone without the use of heat. An improvement in rheotechnological characteristics has been recorded, a water-reducing effect has been established, and an increase in the shelf life of the concrete mixture has been established, which is no less important when concreting large-sized structures or transporting semi-finished products over long distances. Conclusion. The proposed research results will make it possible to successfully implement projects of global importance, creating stable, strong and durable concrete structures.
