Batimix Retarder 220

Concentrated set-retarding and plasticizing admixture for concrete


BATIMIX Retarder 220 is a synthetically produced liquid set-retarding admixture for concrete based on modified gluconate organics blended with selected plasticizing polymers. It does not contain any potentially corroding ingredient that could attack steel, aluminum, or zinc embedments.

Main Purpose

BATIMIX Retarder 220 delays setting times, increasing both workability and slump retention required for proper concrete placing and finishing operations, particularly in hot climates. It is required for concrete that needs to be transported over long distances. It keeps the concrete from hardening should delivery schedules be lengthened by traffic jams.

BATIMIX Retarder 220 improves slump retention over time, eliminating cold joints between adjacent concrete layers. It is particularly suitable for large concrete-pours and slow casting rates.

It is used to produce plain and reinforced concrete castings such as precast, ready-mixed, lightweight, structural, and architectural, with a delayed setting. It is also used to enhance the flowability of pumped concrete.


Concrete prepared with BATIMIX Retarder 220 is characterized by the following:

In the plastic state:

  • Prolonged and controlled rates of setting
  • Improved workability for similar W/C values
  • Reduced cold joints or other discontinuities
  • Improved slump retention and finishing times

In the hardened state:

  • Reduced water permeability and cracking
  • Non-staining and better surface appearance
  • Improved concrete durability
