Perma Multi Plast

ASTM C 494 : Types A, F & G
IS : 9103-2007

Perma Multi Plast is a unique admixture based on complex polymeric chemical structure which works wonderfully with all grades of concrete in all weather conditions. It imparts high compressive, tensile and flexural strength to the concrete. This admixture is of immense use in making the concrete highly workable and in retaining the workability over long hours.

Perma Multi Plast


Mix the admixture with water in the given proportions and dose at the rate 0.5 % to 2% by weight of cement of the diluted material. The dosing of the admixture is done along with the dosing water in the mixture drum. Addition of admixture to the dry cement should be avoided. Should the need arise, to maintain the workability over long hours an additional dosage of admixture can be added to the concrete before the effect of the previous dosage wears off.

  1. Perma Multi Plast is recommended in all types of concrete.
  2. Perma Multi Plast is recommended in hot weather concreting where workability retention over long periods is required.
  3. Perma Multi Plast is also recommended where very high initial and ultimate strengths are expected.


  1. Multi plasticising action of this product produces free flowing concrete, with most kinds of aggregates and varying fine aggregates.
  2. Perma Multi Plast maintains the workability over long periods.
  3. Perma Multi Plast helps in production of high quality concrete which exhibits superior compressive, tensile and flexural strengths and exhibits excellent resistance to chloride and sulphide attacks on concrete.
  4. Perma Multi Plast is compatible with all types of cements including pozzolonic and fly ash/slag cements.
  5. Perma Multi Plast is specially suggested in all high strength concrete.
  6. Perma Multi Plast enables production of dense impermeable and fair finish concrete.
