Technical Information

Concreting Guidance

Concrete placing: With the use of Sika® ViscoCrete®-151, concrete of highest quality is being produced, however state of the art Concrete technology, such as mixing, placing vibrating and curing must be respected and applied.
Curing: Effective measures for concrete curing must be followed

Specific Advice

Sika® ViscoCrete®-151 is added to the mixing water prior to its addition to the dry mix or added separately to the wetted concrete mix.
For optimum dispersion, we recommend a minimum mixing time of 60 seconds.
When adding the balance of the batching water to adjust concrete consistency this should be done after a minimum of 2/3 of the wet mixing time to avoid surplus water in the concrete.

Application

Application Information

Compatibility
