Perma Plast - EX

PRIMARY USES

  1. To increase workability.
  2. To increase compressive strength.
  3. To affect cement economics.
  4. For hot weather concreting.
  5. For waterproofing of concrete and mortar.

TYPICAL APPLICATIONS

  1. In areas of congested reinforcement where high workability is beneficial.
  2. In pre-cast concrete manufacturing.
  3. In concrete brick and block manufacturing.
  4. For hot weather concreting.
  5. For waterproofing of concrete and mortar.

ADVANTAGES

  1. Increases workability.
  2. Improves cohesive property in concrete.
  3. Reduces water demand in concrete.
  4. Reduces permeability in concrete and mortar.

ACTION

Perma Plast-EX is a plasticiser cum integral waterproofing compound which disperses and deflocculates the cement particles within a concrete mix. It can be used to improve workability without the addition of extra water or to allow reductions in free water content of the concrete mix.

DOSAGE

Field trials should be conducted to determine the optimum addition rates of Perma Plast-EX. A dosage range of 100 ml to 500 ml per 50 kgs of cement is recommended as an initial starting point. For waterproofing work the dosage shall be 100 ml per 50 kg bag of cement. In demanding situations the dosage could be doubled.

DIRECTION FOR USE

Perma Plast-EX should be added to the concrete mix during the mixing cycle at the same time as the water. Never add Perma Plast-EX to dry cement.

PROPERTIES

Typical properties of Perma Plast-Ex are as follows:

Colour : Dark brown/black liquid
Specific Gravity : 1.17at 25°C
Air Entrainment : 1% maximum dependent on grading of sand and water content.
 Chloride Content : Free from added Chlorides
 Nitrate Content : NIL

COMPOSITION

A liquid admixture based upon refined lignosulfonates.

HEALTH AND SAFETY

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