Polycarboxylate Ether Powder

“Polycarboxylate ether (PCE) is a ready to use high range water reducing concrete admixture emanating from the stateof- the-Art Polycarboxylate technology. It is new generation superplasticizer containing carboxylic (COOH) group instead of sulphonic (SO3H) as in case of Melamine or Naphthalene Formaldehyde Sulphonate.

Nature: Synthetic polycarboxylic Ester.   |    CAS Number : 70789-60-6

Properties: The power packed (COOH) moiety is absorbed on hydrating cement grain in much greater amount than conventional superplasticizer, resulting excellent fluidity and yielding a Rheoplastic & Self Compacting Concrete (SCC) at low water cement ratio. Due to steric-hindrance effect imparted by ether-function hydrophilic chain attached to polymer, superior slump (workability) retention is achievable by use of PCE. PCE is compatible with lingo base plasticizer. Do not use blending with SNF base plasticizer. PCE is the main raw material for concrete admixture, which improves water reducing abilities. We provide first rate products through continuous quality control and usage development.

Advantage: The advantage of PCE are as below,

  • High water reducing ability.
  • Easy to use any cement grade.
  • Improve concrete setting time.
  • Produces cohesive and non-segregating concrete mixtures.
  • Small dosage level.
  • Low concrete viscosity.
  • Increase compressive and flexural strength of concrete at all ages.
  • More than 30 % water reduction in high performance concrete.
  • Linear water reduction throughout the recommended dosage.
  • Faster recycle of formwork owing to accelerated early strength development.
  • Close textured fair faced smooth concrete.
  • Rheoplastic self-leveling and self compacting concrete.
  • Economical concrete design.

Dosage: 0.1 to 0.5 kilograms/100 kilograms cementitious material for most concrete mixes using typical concrete ingredients. However for silica fume concrete, the dosage may fall outside recommendation and site trials in case of critical workability and setting time parameters as per requisites to fix optimum dosage. To be mix with water and added to cement aggregate mixture.

Packing : PCE Powder is available in 25 kg paper bag. Alternative packing sizes may be available upon request.
