Sika® ViscoCrete®-6008 NS may be combined with many other Sika® Products.

Compatible with all types of cement and cementitious materials.

Important: Always conduct trials before combining products in specific mixes and contact our Technical Service Department for information about specific combinations.

DISPENSING

Sika® ViscoCrete®-6008 NS can be added into the mixing water or directly into the concrete mixer after 50 – 70% of the mixing water has been added.

The addition of Sika® ViscoCrete®-6008 NS to dry aggregate or cement is not recommended.

To achieve optimum performance a minimum wet mixing time, which is depending on the mixing conditions and the mixer performance, of 60 seconds is recommended.
Consumption

Recommended Dosage

Standard dosage will vary from 0.5% to 1.5% by weight of cement. Exact dosage rates are dependent on the quality of cement, aggregates,
water/cement ratio and ambient temperature. Therefore, in many cases it is advisable to carry out trial mixes.
Higher dosage may be used if agreed by engineer and consultant.
Stir well before use.
