Perma Plast AC


Concrete Accelerator Admixture


IS : 9103-2007
IS : 2645-2003


Perma Plast AC is a silicate based liquid which acts as a plasticising accelerator for cement, concrete and mortar. Perma Plast AC admixed mortars and concretes set fast giving early and final high strength. Perma Plast AC is of special use in shot-creting,guniting, plasticising and concreting in very low temperatures.

Concrete Accelerator Admixture


  • In fast setting of concretes and mortars.
  • Concreting of pre-cast elements.
  • Concreting and rendering in very low temperatures.
  • In reducing rebound losses in sprayed mortar.
  • To impart waterproofing properties to concrete & plaster.


  • Perma Plast AC is of special use in plastering mortar, guniting and shot-creting as its accelerated setting times help in quick rebuilding of mortar layers without collapse.
  • Rebound losses in plaster mortar, shot-creting and guniting are minimized. Early shifting of the pre-cast elements is facilitated.
  • In pre-cast hollow/solid blocks, pavers, cement tiles, breaking of the edges while lifting the moulds is minimized.
  • Perma Plast AC helps in early setting of mortars and concrete in low temperature climates.


  • Rebound losses in plastering mortar, shot-creting and guniting are minimized. Saving on material, labour and machine time.
  • Perma Past AC is in liquid in form, hence easy to use.
  • The plasticizing action of Perma Plast AC helps in complete hydration of cement there by achieving superior strength.
  • Wastage due to breaking in pre-cast elements is reduced hence savings on production cost.
  • Perma Plast AC can be used with all types of cements.
  • To waterproof plaster and concrete.
  • Perma Plast AC helps in achieving high early strength to the mortar & concrete hence breakages of hollow blocks & pre cast members are minimized.


In case of shot-creting / guniting , Perma Plast AC is mixed in the gauging water in the required proportion before addition to the dry mix. Hence it can be successfully used in both dry and wet shot-creting processes. In concrete and mortars for pre -casting elements. Perma Plast AC is dosed through a separate dosing tank fitted above the mixer. It can be dosed manually as well as after addition of required water.


Required dosage of Perma Plast AC has to be arrived at site by practical trials. The dosage is dependent on temperature conditions, type of cement, type of acceleration required. We however recommend dosages of 1 to 10 percent by weight of cement. Lower dosages are however used in pre-cast elements and higher dosages are used in shot-creting. For waterproofing the minimum dosage of the product shall be 250 gms/50kg bag of cement.

  • Over dosage of Perma Plast AC results in flash setting on concrete or mortars.
  • Do not use frozen aggregates while concreting at low temperature areas.
  • For best results keep gauging water to a minimum.
  • Areas to be concreted or shot-creted should be free from ice.
  • Fresh concrete should be so sheltered as to ensure the preservation of heat of hydration evolved.
  • The rules laid down by concreting authorities for cold weather should be strictly followed.


Perma Plast AC is compatible with all types of portland cements including sulphate resisting cement. For use with other cements and along with other admixtures Please seek the advice of your nearest Perma technical officer or Distributor. Perma Plast AC should not be premixed with other admixture. If other compatible admixture to be used in concrete then dose them separately.


Perma Plast-AC is not a health hazard or fire risk. Spillages should be washed immediately to avoid possibility of slipping.


Perma Plat AC is available in 100gm, 500gm, 1kg, 5kg, 10kg, 20 kg, 30 kg and 120 kg & 250 kg packs.


Perma Plast AC has a shelf life of 24 months if stored in Manufacturer’s original packing.
