Concrete superplasticizers-plastit SPN1

Plastit SPN1 is a chloride free, superplasticising admixture based on selected polymer modified napthalene sulphonate dispersives. Plastit SPN1 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 contentsensures improved durability
 Improved cohesion and particle dispersion minimizes segregation and bleeding and improves pumpability Chloride free, safe for use in precast, prestressed and reinforced concrete

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

The optimum dosage of Plastit SPN1 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 0.5% to 1.5% by weight of cement may be used

Packaging
 Plastit SPN1 is available in 20 kg containers and 240 kg drums.
 Storage
 Plastit SPN1 has a minimum shelf life of 12 months provided the temperature is kept within the range of 5°C to 35°C. Should the temperature of the product fall outside this range then contact CAPCO for advice. Freezing point: Approximately -2°C
