When building in a hot climate there is a problem of workability of the concrete mix, affecting the human labor, time and cost of construction. The subject of survey is the effect of additives on the properties of concrete superplasticizer different classes. In tests used superplasticizer KR 501 companies «SanNopca Korea», provided by «Uneedus Group» LLP. The use of this additive has increased the setting time of the concrete mix, improve water resistance, while maintaining the physical properties of concrete within the permissible limits. Confirmed the effectiveness of liquid superplasticizer based on polycarboxylate polymers in the summer to control plasticity (workability) of concrete. This additive has found its application in the construction of residential units in the southern regions of Kazakhstan.
