Influence of superplasticizers on the concrete mix properties

Abstract

The most important technological properties of concrete mix are its workability, waterproof capacity, immutability of the properties and air-entrainment. The task of increasing the efficiency and quality of concrete and reinforced concrete is still very relevant and it cannot be successfully solved without the use of special chemical additives. The purpose of the research is to obtain workable concrete mix using special additives. The plasticizers based on polycarboxylate esters: Power Flow PF-2695, Power Flow PF-1130 and Power Flow PF-2237 have been determined as the most effective. It was found that some additives after the addition cause the creation of defects.
