Perma Concrete Set

ACCELERATING ADMIXTURE FOR CONCRETE AND MORTAR
SPECIFICATION

Perma Concrete Set is a chloride based accelerating admixture for use in non reinforced concrete and mortars. When admixed with concrete and mortar along with water Perma Concrete Set accelerates the setting time of the concrete and mortar and helps in achieving high early strength. This product is of use in shot-creting and guniting and in concreting and rendering in cold climatic conditions. Paver industry can highly benefit from the use of this product as it helps in early de-moulding and early shifting of the paver blocks to site saving enormous amount of space utilized in conventional curing and its strength development.

Perma Concrete Set

PRIMARY USES

  1. In fast setting of concretes and mortars
  2. Concreting of pre-cast elements
  3. Concreting and rendering at very low temperatures
  4. In reducing rebound losses in sprayed mortars
  5. In paver block industry
  6. In casting yards of hollow and solid building blocks

ADVANTAGES

  1. Rebound losses in plastering mortar, shot- creting and guniting are minimized. Saving on material, labour and machine time.
  2. Perma Concrete Set is in liquid form, hence easy to use.
  3. The plasticizing action of Perma Concrete Set helps in complete hydration of cement there by achieving superior strength.
  4. Wastage due to breaking in pre-cast elements is reduced hence savings on production cost.
  5. Perma Concrete Set can be used with all types of cements.
  6. To waterproof plaster and concrete.

DIRECTIONS FOR USE

In case of shot-creting / guniting, Perma Concrete Set is mixed in the guaging 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 and for pre-casting elements. Perma Concrete Set is dosed through a separate dosing tank fitted above the mixer. It can be dosed manually as well after addition of required water.

DOSAGE

Required dosage of Perma Concrete Set 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.

CAUTION

  1. Over dosage of Perma Concrete Set results in flash setting of concrete or mortars.
  2. Do not use frozen aggregates in concreting in low temperature areas.
  3. For best results keep gauging water to a minimum.
  4. Areas to be concreted or shot-creted should be free from ice.
  5. Fresh concrete should be so sheltered as to ensure the preservation of heat of hydration evolved.
  6. The result laid down by concreting authorities for cold weather should be strictly followed.

COMPATIBILITY

Perma Concrete Set 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 Concrete Set should not be premixed with other admixtures. If other compatible admixtures are to be used in concrete then dose them separately.

PACKING

Perma Concrete Set is available in 30 Kg & 120 Kg HDPE Drum

SHELF LIFE

Perma Concrete Set has a shelf life of 24 months if stored in manufacturer’s original packing in a cool and dry place away from moisture and heat.
