What these products do

Water reducing admixture

Lets you use less water for the same workability, or get better workability at the same water. Normal water reducers give a modest reduction.

High range water reducer

Also called a superplasticiser. Gives a large water reduction and makes low water cement ratio, high strength and self-compacting concrete possible.

Retarder

Delays setting. Useful in hot weather, long transport and large pours.

Accelerator

Speeds up setting and early strength. Useful in cold weather or when early de-shuttering is needed. An alkali free grade is also available.

Corrosion inhibitor

Helps protect reinforcement steel from corrosion in concrete.

Good practice

  • Run a trial mix with your own cement, aggregates and water before using at scale. Results change with the cement.
  • Add the admixture with the mixing water, not on dry cement.
  • Do not mix two admixtures together before dosing unless their compatibility is confirmed.
  • An admixture helps a good mix. It does not fix a poor one.

Accelerating, retarding, water reducing and superplasticising admixtures are classified in IS 9103.

General guidance only. Always follow the product datasheet and your project specification.
