Methods for restoring the mobility of a concrete mix

The relevance of the study is due to the fact that currently monolithic construction is characterized by a high rate of construction work, since in modern market conditions this indicator determines the final cost per square meter. As it is known, the life cycle of any concrete product or structure includes the preparation of a concrete mixture, transportation, laying, sealing, hardening and further operation.Therefore, the initial stage of the life cycle – the preservation of the properties of the concrete mixture over time will determine the technological and physico-mechanical properties, respectively, of the concrete mixture and concrete. An aggravating factor in maintaining the properties of the concrete mixture in the summer is the air temperature exceeding 30оC. The paper shows technological techniques that make it possible to level the temperature factor on the properties of the concrete mixture over time.It was found that the introduction of superplasticizers in the amount of 1% of the cement mass and the restoration of mobility at the construction site make it possible to obtain concretes with specified qualities. This study is relevant for manufacturers of concrete mixtures.
