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-C 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.
For powder: Woven plastic bag with film liner. Net weight: 25kg +/- 0.2 kg.
