Dispensing

For maximum efficiency, add Sika ViscoFlow®-12 directly to freshly mixed concrete in the concrete mixer after all batching water and water reducing admixture has been added. Sika ViscoFlow®-12 may also be dispensed into freshly mixed concrete in the agitator truck, at the concrete plant or at the job site. To optimize the slump retaining effect, Sika recommend that the combined materials should be mixed for 80-100 revolutions either in the concrete mixer or in the agitator truck.
Consumption

Recommended Dosage

Recommended dosage is 200 to 1000 ml per 100kg of total cementitious material. Optimum dosage should be determined by site trials.
