PRIMARY USES To produce self-compacting flowing concrete. To produce high early strength concrete. |
||||||||||||
| 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. Suitable for use with Microsillica. General structural concrete which requires minimal labour to place. |
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- PS34. 2) High strength mixes - Due to reduction in water content higher grade concrete can be produced at normal workabilities and cement contents. 3) Improved Compaction - Concrete can be placed and compacted more quickly and easily when Perma Plast-Super-PS34 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-PS34 should be added to the mix during the cycle at the same time as the water or the aggregates. Never add Perma Plast-Super-PS34 to dry cement. No extention to mixing time is necessary. Alternatively when using Perma Plast-Super-PS34 to produce flowing concrete at site using ready mix trucks, it can be added to the concrete via the hopper 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-PS34 dramatically increases the workability of concrete mixes by it's 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-PS34. As a guide to these trials, the following figures are recommended as a starting point: Water Reduced Concrete Dosage % WaterReduction (cc per 50 Kgs.of Cement)
|
EFFECTS OF OVER-DOSAGE A severe over dosage of Perma Plast - Super-PS34 will make the concrete free flowing and may result in bleeding. The strengths obtained however will be in excess the designed strengths. |

| HEALTH AND SAFETY Perma Plast-Super-PS34 is not a health hazard or fire risk. Spillages should be washed immediately to avoid possibilities of slipping. |
|||||||||||||
| SHELF LIFE Twelve months if stored in manufacturer’s sealed drums. |
PACKING Perma Plast-Super-PS34 is available in 24 kgs and 250 kgs drum. |
