0.5 – 1.5% by weight of cement. 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.

?

SNF-B can be added directly or added in after dissolved in water. It can be added during

mixing and after-mixing (better). The after-mixing approach can achieve better result.
