Product Overview

 

ViscoCrete® powder polycarboxylate PCEs are a series of high range water reducing superplasticisers for use in dry mix applications in general, and mortars and SLUs in particular. The polycarboxylate polymer powders have been optimised to effect a maximum of water reduction.

ViscoCrete® products are highly effective superplasticisers, which have an electrosteric repulsion effect on the cement and aggregate particles in a mortar or grout once mixed with water.

  • Free-flowing powder
  • Conforms to EN 934-2, Table 3.1/3.2
  • Alkali content <= 2.0% (Na2O equivalent)
Product Benefits
  • High water reduction at low dosage: results in shorter drying times, and higher densities and strengths
  • Reduced processing and compaction efforts due to very good flow and self-levelling behaviour
  • Reduced mixing time due to fast adsorption
  • Improved shrinkage and creep behaviour
  • Free of formaldehyde and ammonia
  • Compatible with other additives
Typical Applications
  • Calcium sulphate and cement-based screeds
  • Self-levelling screeds and underlayments
  • Non-shrink and anchor grouts, tile adhesives, injection and repair mortars
  • Building plaster, render, stucco, bonding/filling compound, moulding plaster, dental and medical plaster
