Concrete Superplasticizers-Plastit® SPL90

Plastit SPL90 is a chloride free work ability retention admixture based on selected specially selected and blended organic polymers. It is supplied as a brown solution which instantly disperses in water. Plastit SPL90 disperses the fine particles in the concrete mix, enabling the water content of the concrete to perform more effectively. The increased work ability, cohesion and retardation minimizes loss of workability

 Good slump retention
 Suitable for ready mix & hot weather concreting
Makes possible major reductions in water:cement ratio which allow the production of high strength concrete without excessive cement contents
 Improved cohesion and particle dispersion minimizes segregation and bleeding and improves pumpability Chloride free, safe for use in prestressed and reinforced concrete

Increases work ability without extra water, reducing placing time and costs
 Gives increased working life to fresh concrete. - Improves cohesion, minimizing segregation and improving surface finish
 Aids pumping by improving cohesion and reducing work ability loss
  Allows a reduction in water:cement ratio, enhancing durability by producing low permeability concrete with reduced shrinkage cracking potential
 Chloride free, safe for use in prestressed and reinforced concrete. - Can be used with concrete containing micro silica and other cement replacements

The optimum dosage Plastit SPL90 to meet specific requirements should always be determined by trials using the materials and conditions that will be experienced in use. The normal dosage range is 0.3 to 1.2 kg/100 kg of cementitious material, including PFA, GGBFS and microsilica


Appearance Brown Liquid
Specific gravity 1.16 gr/cm3 at 20°C

Plastit SPL90 is available in 20 kg containers and 240 kg drums
Plastit SPL90 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 -3°C
