A HIGH RANGE, LOW DOSAGE, SUPER PLASTICISING ADMIXTURE FOR SLUMP RETENTION
To produce self-compacting flowing concrete. To produce high early strength concrete for delayed slump retention & for long overhauls.
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.
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.
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.
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
|% Water Reduction
||(gms per 50 Kgs. of Cement)
|10 to 15
|15 to 20
|20 to 30
|30 to 35
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.
A multicomponent liquid admixture based on high molecular weight polymers and Naphthalene formaldehyde.
HEALTH AND SAFETY
Perma Plast Super is not a health hazard or fire risk Spillages should be washed immediately to avoid possibilities of slipping.
Perma Plast Super is available in 30 kg, 120 kg and 250 kg drum.
Perma Plast Super has a shelf life of 24 months if stored in manufacturer’s sealed drums.
