Mar 22, 2014 · What is the super plasticizer? Superplasticizers are used to enhance the fluidity of the concrete without adding water. Molecules physically separate the cement particles, these molecules ...

The naphthalene superplasticizer (SNF/PNS/FDN) is a type of high range superplasticizer, and the appearance is light brown powder. It is very soluble in water , and the water reduction rate is up to 25%. Besides, it is commonly referred to as a super plas

ConstraChem products are in the form of chemicals admixtures, precast admixtures, admixtures used by ready mix concrete plant, precast admixtures used by concrete plant and concrete additives which reduce usage of water, improve durability and workability

Concrete admixture-Water reducer-Super plasticizer. By reducing the amount of water. The cement paste will have higher density, which result in higher paste quality. An increase in paste quality will yield higher compressive and flexural strength, lower

A water reducing chemical, as the name implies, is used to reduce the water content of a concrete mixture while maintaining a constant workability. The resultant effect of the reduced water content is the increased strength and durability of concrete.

Various Types of Concrete Additives: Kingsun concrete additives for strength can be liquid or powder. And these additives in concrete mainly include high range water reducing admixtures( Naphthalene Based Superplasticizer , Polycarboxylate Superplasticize

Superplasticizers, also known as high range water reducers, are chemical admixtures used where well-dispersed particle suspension is required. These polymers are used as dispersants to avoid particle segregation (gravel, coarse and fine sands), and to imp

When added to concrete at a rate of 2% by weight of cementitious material, SRA-157 can reduce shrinkage by up to 80% at 28 days of age and by up to 50% at one year of age. MP-10 is a high-performance, efflorescence-reducing, water-repelling admixture for
