Polycarboxylate superplasticizer is the thrid generation concrete superplasticizer which advance developed from lignosulfonate calcium type and naphthalene type superplasticizer.
Polycarboxylate superplasticizer is a modify concrete superplasticizer researched by new technology.it is a green environmental product with good comprehensive index and no pollution.
Polycarboxylate superplasticizer is the latest type concrete superplasticizer with higher water reducing ratio and better slump retention performace than the former two types concrete admixture.
Main classification of polycarboxylate superplasticizer
According to product appearance,there are mainly two types:liquid type and powder type.
for liquid type,there are different solid content,like 40%,45%,50% and even 60% solid content.but from our sales experience,it seems that 50% solid content polycarboxylate superplasticizer is most popular internationally.for 50% solid content polycarboxylate superplasticizer is freight cost saving compare with 40% and 45% solid content,besides its cost performance ratio of concrete performance is very competitive.
In recent years,lots of factories begin producing powder type for polycarboxylate superplasticizer.of course,powder type is more convenient for delivery.according to usage difference,there are mortar used type,floor used type and concrete producing used type,etc.
Main characteristic of polycarboxylate superplasticizer
perfect slump retention performace
high water reduction rate
excellent adaptability with all kinds of cement
