polycarboxylic acid superplasticizer chemicals for concrete

Naphthalene superplasticizer is the largest production volume in China, the most widely used high efficiency superplasticizer (accounting for more than 70% of the amount of superplasticizer), which is characterized by high water reduction rate (15% ~ 25%), no air entraining, little impact on setting time, relatively good adaptability with cement, can be used with other kinds of admixtures, and the price is relatively cheap. Naphthalene superplasticizers are often used to prepare large flow, high strength and high performance concrete. The slump loss of concrete with naphthalene superplasticizer is faster. In addition, the adaptability of naphthalene superplasticizer to some cement needs to be improved.
