Conplast P211 is a chloride free water reducing admixture based on selected sugar-reduced lignosulphonates. It is supplied as a brown solution which instantly disperses in water.
Conplast P211 disperses the fine particles in the concrete mix, enabling the water content of the concrete to perform more effectively and improving the consistency of the concrete. This produces higher levels of workability for the same water content, allowing benefits such as water reduction and increased strengths to be taken.

It confirms to IS:9103-99. Also complies with IS:2645-2003 & ASTM C494 Type A.

Advantages 

  • Allows specified strength grades to be met at reduced cement content or increased workability.
  • Water reduction significantly improves compressive strengths at all ages and enhances durability through the production of low permeability concrete.
  • Minimises the risk of segregation and bleeding and assists in the production of a dense, close textured surface, improving durability.
  • Chloride free, safe for use in prestressed and reinforced concrete.

  • Increase workability
  • Increase compressive strength by reducing water content
  • Reduces cement content without altering workability and strength
  • Increase durability of concrete by reducing water permeability
  • Chloride free, hence safe for reinforced concrete

Dosage
The optimum dosage of Conplast P211 to meet specific requirements should always be determined by trials using the materials and conditions that will be experienced in use. This allows the optimisation of admixture dosage and mix design and provides a complete assessment of the concrete mix. A starting point for such trials is to use a dosage within the normal typical range of 0.20 to 0.50 litres / 100kg of cementitious material, including PFA, GGBFS and microsilica.

Packing
Conplast P211 is supplied in 5,20 and 200 litre containers.

Storage
Conplast P211 has a minimum shelf life of 12 months provided the temperature is kept within the range of 200C to 400C. Should the temperature of the product fall outside this range then the Fosroc Technical Service Department should be contacted for advice.
