Sulphonated Naphthalene Formaldehyde

SNF acts as a superplasticizer by neutralizing the surface charges on the cement particles and enhancing water tied up in the cement agglomerations and thereafter reducing the viscosity of the concrete paste. It promotes dispersing of cement particles and reduces water demand.
Carboxylic Acid Copolymer
This product acts as water reduction type superplasticizer that offers high fluidity and workability to concrete mixes.
Sodium Silicate
Sodium Silicate is used in cement and concrete applications. Liquid silicates are used extensively as penetrating concrete sealers. The silica reacts with free calcium in the concrete and forms calcium silicate hydrate. This helps to make the concrete surface more abrasion-resistant, more chemically resistant, harder and less permeable.
As a cement admixture, liquid or powdered silicates are added to cements to accelerate the set. Liquid silicates used in shotcreting or gunning provide immediate set.
It is also used in oil well cements that have a relatively high water content, Sodium silicate can be added to help prevent segregation of the solids from the water.
