Sika® ViscoCrete®-3969 Ease

(former MasterEase® 3969)

Superplasticizer for the production of high quality ready-mix concrete with enhanced rheology

Sika® ViscoCrete®-3969 Ease is an innovative superplasticizer designed to give class-leading rheology and workability.
Sika® ViscoCrete®-3969 Ease is formulated from unique polymers. The objective of the development of this new, next generation polymer was to take the characteristics of traditional polycarboxylic ether (PCE) admixtures but to give enhanced rheology and robustness to the concrete.
The polymers contained in the formulation of Sika® ViscoCrete®-3969 Ease ensure that enhanced rheology is maintained from time of mixing to time of placing and finishing.

For the Ready-mix Producer:
  • Capability of delivering high performance concrete with enhanced rheology.
  • Concrete is easier to pump reducing pumping time and pumping pressure and thus wear-and-tear on equipment.
  • Concrete is easier to place and finish.
  • Enhanced rheology is maintained from time of mixing to time of placement.
         For the Contractor / Applicator:
  • Easier placing and improved strength development
  • Improved concrete surfaces
        For the Engineer:
  • Insurance that concrete meets original specification
  • High quality durable concrete.

Application

Application Information

Dispensing

Sika® ViscoCrete®-3969 Ease is a ready-to-use admixture to be added to the concrete as a separate component.

Optimal result is obtained if Sika® ViscoCrete®-3969 Ease is poured into the concrete mix right after the addition of the first 80% of the mixing water, i.e. when all solids are wetted.

Avoid adding the admixture to the dry aggregates.
Consumption

Recommended Dosage

The normally recommended dosage rate of Sika® ViscoCrete®-3969 Ease is:

0.5 to 1.5 litre per 100kg of total cementitious material.


Other dosages may be recommended in special cases according to the specific site conditions. In this case, please consult our Technical Services Department for advice.
