Sika® ViscoCrete®-3626 Ease

(former MasterEase® 3626)

Superplasticizer to produce high-quality precast concrete with enhanced rheology

Sika® ViscoCrete®-3626 Ease is one of the latest products developed as a result of our ongoing innovation drive. Based on a new, and patented polymerisation process, Sika® ViscoCrete®-3626 Ease is specifically developed for use in the precast industry. Sika® ViscoCrete®-3626 Ease has been developed to provide an improved concrete rheology without compromising the early strength development of the concrete and improved final concrete strengths.
The polymer structure of Sika® ViscoCrete®-3626 Ease is specially designed to improve the rheology of precast concrete, to allow for very flowable and with low viscosity even at very low water/cement ratios. Robustness, surface finish and retention performance are a distinctive feature of the precast concrete produced with Sika® ViscoCrete®-3626 Ease.
Thanks to its tailored mode of action in concrete, Sika® ViscoCrete®-3626 Ease imparts a level of viscosity within a mix enabling the right balance between fluidity, passing ability and resistance to segregation to be achieved.  

Sika® ViscoCrete®-3626 Ease offers the following benefits for the concrete industry:
  • Production of high slump concrete or highly flowable, robust self-compacting concrete having a low water cement ratio along with an optimal rheology.
  • Concrete is easier to place and finish.
  • Enhanced rheology is maintained from time of mixing to time of placement.
  • Insurance that concrete meets original specification
  • High quality, durable precast concrete elements
  • Improved surface appearance
  • Elimination or reduction of the energy required for placing, compaction and curing.
  • Enables SCC (Self-compacting concrete) with re-duced fines content.

Application

Application Information

Dispensing

Sika® ViscoCrete®-3626 Ease is a ready-to-use admixture to be added to the concrete as a separate component. Optimal result is obtained if Sika® ViscoCrete®-3626 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®-3626 Ease is 0.45 to 1.50 Litre per 100kg of total cementitious material.
Other dosages may be recommended in special cases ac-cording to the specific site conditions. In this case, please consult our Technical Services Department for advice.
