Concrete Superplasticizers-Plastit® SPN215

Plastit SPN215 is a chloride free, superplasticising admixture based on selected polymer modified napthalene sulphonate dispersives. Plastit SPN215 disperses by electro kinetic action in the concrete mix, enabling the water phase of the concrete to perform more effectively.

 High range water reducing property allows the production of high quality concrete without excessive cement contents ensures improved durability 
Improved cohesion and particle dispersion minimizes segregation and bleeding and improves pump ability 
 Chloride free, safe for use in precast, prestressed and reinforced concrete

 Specifically developed for use in high quality concrete for work ability retention at low water content
 Provides good pump able concrete - Recommended for piling and mass concrete pours with improved cohesion

The optimum dosage of Plastit SPN215 to meet specific requirements should always be determined by trial mixes using the materials and conditions that will be experienced in use. For normal concrete a dosage between 0.4% to 1.5% by weight of cement may be used
