Setting retarder admixtures

CONPLAST R - Setting retarder/ water reducing admixture and CONPLAST P211 – Plasticizer/ water reducing/ setting retarder


Product that extends the starting time of the concrete transition from the rigid to plastic state, while maintaining the consistency of the reference concrete


  • Increase setting time while extending the time of put into work
  • Extends the work time of semi-dry concrete
  • Improves the put into work for the too cohesive mixtures
  • Does not contain chlorides


Product that allows either the required mixing water content’s reduction in fresh concrete without affecting its consistency or the increasing of the workability while maintaining the same water content, or both effects together. At dosages between 0.5-0.7 l/100kg cement can be used as an additive to delay setting and reduce permeability.


  • Its main role is to reduce water to equal consistencies but at double dosage has also role of waterproofing and setting retarder
  • Increases the workability
  • Increases the concrete strength without increasing the amount of cement .
  • Increases the durability, decreases the permeability and the risk of cracking .
  • Does not contain chlorides or alkali
