Abstract

The paper presents the results of studies the role of modern chemical, mineral and micro-reinforcing additives in the process of structure formation of high-strength concrete. The paper reveals the features of the structure formation of cement stone in the presence of a superplasticizer. The paper experimentally proves that, according to the test results, the best performance on the persistence of concrete mixtures has a superplasticizer "Linamix PC" while this additive has the lowest consumption (1.1% by weight of cement). The specified grade for workability on this type of additive is maintaining for 4-5 hours, and the mixture becomes stiff after 7 hours of mixing, while the concrete grade (P5) is lost after 3 hours. It has been established that the persistence of concrete mixtures can be increased up to 8-10 hours by using the "Linamix RS" additive jointly with the "Linamix PC" superplasticizer slowing down the mixture hardening rate by 2 times or more, which is very important in continuous monolithic concreting at various construction sites.
