Sika® ViscoCrete® PC HRF-1

High Range Water Reducer - HWR

Sika® ViscoCrete® PC HRF-1 is a new generation, powerful, superplastisizing concrete admixture for demanding concrete applications.

Sika® ViscoCrete® PC HRF-1 has the following characteristics and advantages:
  • Very high water reduction can be used to achieve durability, high early and late-age strenghts, improved shrinkage and creep behaviour, lower cement contents and super-workable concrete mixes.
  • The neutral-set characteristics provide quicker setting and finishing times, high early strenghts and early stripping and demoulding of pre-cast products.

Technical Information

Specific Advice

Sika® ViscoCrete® PC HRF-1 is added to the initial batch water. For optimum utilisation of the high water reduction we recommend thorough mixing at minimum wet-mixing time of 60 seconds per cubic metre.

The addition of the remaining guaging water, to fine tune concrete consistency, should only be started after 2/3rds of the wet mixing time, to avoid surplus water in the concrete.

Sika recommend Sika® ViscoCrete® PC HRF-1 be restricted for use in site-batched concrete or for short travel times, because of the early loss of workability.

Application

Application Information

Compatibility

Sika® ViscoCrete® PC HRF-1 can be used in conjunction with the following Sika products:

  • Sika Plastiment Series
  • Sika Rapid
  • Sika Ferrogard 901
  • Sika Fume
  • Sika ViscoFlow
  • Sika Retarder

All admixtures must be added separately. Trial mixes are necessary to confirm plastic and hardened concrete properties.

Restrictions

  • Do not use with naphthalene-based concrete admixtures.
  • Do not add to dry cement.
  • Trial mixes are necessary to ensure compliance with the required/specified plastic and hardened concrete properties.
Consumption

Recommended Dosage

Typical dose rates range from 200-1000ml per 100kg of total cementitious material.
