Application

Application Information

Dispensing

Sikament® NN TH can be added separately to the freshly mixed concrete or directly to the mixing water prior to its addition to the aggregates. When added separately to the freshly mixed concrete, further mixing should take place for at least one minute per cubic meter.

Compatibility

Sikament® NN TH may be combined with many other Sika products. Trials must always be carried out before combining products in specific mixes. Contact Sika Technical Services for additional information and any specific combinations.
Sikament® NN TH is compatible with all types of Portland Cement, including SRC type and Hydraulic Cement.
Consumption

Recommended dosage

600 - 3,000 cc. per 100 kg. of cement weight

Exact dosage rates are dependent on the type of effect sought, quality of cement and aggregates,water/ cement ratio and ambient temperature. Therefore, in many cases it is advisable to carry out trial mixes.
