PRIMARY USES
1) To increase workability.
2) To increase compressive stength.
3) To effect cement economies.
4) For hot weather concreting.


TYPICAL APPLICATIONS
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.


ADVANTAGES
1) Increase workability.
2) Improves cohesive property in concrete.
3) Reduces water demand in concrete.


ACTION
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.

 
DOSAGE
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.
