IMPORTANCE OF NEUTRALIZATION OF SUPERPLASTICIZERS FOR CONCRETE MIXTURE

In the neutralization process, diethanolamine was used in an amount from 5% to 30% relative to the superplasticizer mass. The obtained results showed that when diethanolamine was used in an amount of 10% compared to the mass of superplasticizer, the plasticizing property showed the highest result, and the elasticity of the cement mixture was 20 cm. When diethanolamine is used in the amount of 20%, the flowability is 16%, when 25% is used, the flowability is 14cm, and when diethanolamine is used in 30%, the superplasticizer obtained when applied to the cement mixture shows the lowest plasticizing property and is 11cm. It can be seen that in the process of neutralizing the superplasticizer with diethanolamine, a superplasticizer with the highest plasticizing properties was obtained when 5% of the superplasticizer mass was used from a 20% diethanolamine solution.
