Concrete Superplasticizers-Plastit® SPL1

Plastit SPL1 is a chloride free, superplasticising admixture based on specially selected and blended synthetic polymers. It is supplied as a brown solution which instantly disperses in water. Plastit SPL1 disperses the fine particles in the concrete mix, enabling the water content of the concrete to perform more effectively. The very high levels of water reduction possible allow major increases in strength to be obtained.

 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 SPL1 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 0.3% to 0.8% by weight of cement may be used
