We at Perma constructions aid, provides a wide range of Perma Plast-EX, which is a general purpose plasticizers for concrete. Our product is based upon lingo sulphonates. Our product is well known in the market for being a solid concrete, used as a waterproof on floors, walls etc. We ensure that our Water Proofing Plasticizers is of genuine quality that can be use for construction works.
1) To increase workability.
2) To increase compressive stength.
3) To effect cement economies.
4) For hot weather concreting.
1) In areas of congested inforcement where high workability is beneficial.
2) In pre-cast concrete manufacture.
3) In concrete brick and block manufacture.
4) Fot hot weather concrete.
1) Increase workability.
2) Improves cohesive property in concrete.
3) Reduces water demand in concrete.
Perma Plast-EX is a plasticiser which disperses and deffloculates 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.
Field trials should be conducted to determine the optimum addition rates of Perma Plast-EX. A dosage range of 140 ml to 280 ml per 50 kgs of cement is recommended as an initial starting point.
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.
Typical properties of Perma Plast-Ex are as follows:
|Colour||Dark brown/black liquid|
|Specific Gravity||1.17 at 250C|
|Air Entrainment||1% maximum dependent on grading of sand and watercontent.|
|Chloride Content||Free from added Chlorides|
A liquid admixture based upon refined lignosulphonates.
HEALTH AND SAFETY
Perma Plast-Ex is not a health hazard or fire risk. Spillages should be washed immediatly to avoid possibilities of slipping.
Perma Plast-Ex is available in 2, 20 and 210 litres.
Twelve months if stored in manufacturer's original packing
