Perma Plast Super

PRIMARY USES

To produce self-compacting flowing concrete. To produce high early strength concrete for delayed slump retention & for long overhauls.

TYPICAL APPLICATIONS

For the production of high workability concrete where heavily congested reinforcements exist or poor access is available. To produce flowing self compacting concrete which requires minimal labour to place. For the production of high strength, high workability concrete. Particularly beneficial in hot climatic conditions and in ready mix concrete.

ADVANTAGES

  1. Increased workability-A concrete with a slump of 50 to 100 mm can be turned into self compacting, flowing concrete that requires little or no vibration, with the simple addition of Perma Plast-Super.
  2. High strength mixes – Due to reduction in water content higher grade concrete can be produced at normal workability and cement contents.
  3. Improved Compaction – Concrete can be placed and compacted more quickly and easily when Perma Plast-Super is incorporated to the mix.
  4. Superior Finish – Surface finish is improved, sand runs and blemishes are reduced.
  5. Durable Concrete – Enables production of economical, dense and more permeable concrete.

DIRECTIONS FOR USE

Perma Plast Super should be added to the mix during the cycle at the same time as the water and the aggregates. Never add Perma Plast Super to dry cement. No extension to mixing time is necessary.

Alternatively when using Perma Plast Super to produce flowing concrete at site using ready mix trucks, it can be added to the concrete via the hoper at the rear of the truck a few minutes before use, at a minimum drum revolution of 10 r.p.m. to produce a fully homogenous mix.

ACTION

Perma Plast Super dramatically increases the workability of concrete mixes by its powerful deflocculating and dispersing effect on the cement particles. This increase in workability can be utilised to produce high workability concrete or to enable significant reductions in the free water content.

DOSAGE

Field trials should be conducted to determine the optimum addition rates of Perma Plast Super. As a guide to these trials, the following figures are recommended as a starting point:

Water Reduced Concrete Dosage
% Water Reduction (gms per 50 Kgs. of Cement)
10 to 15 150
15 to 20 310
20 to 30 450
30 to 35 600

EFFECTS OF OVER-DOSAGE

A severe over dosage of Perma Plast Super will make the concrete free flowing and may result in bleeding. The strengths obtained however will be in excess of the designed strengths.
