/ preferably use a central batching

plant mixer / recommended dosage = 1 bag/m³

/ a continuous grading is preferred / mix until all glued steel fibres are

separated into individual fibres.

Fibres don't increase the mixing time

significantly. / if special cements or admixtures are used, =*sr a preliminary test is recommended

Dramix® Duo 100 is a blend of Dramix® and Duomix®. Dramix® fibres are filaments of steel wire, deformed and cut to lengths, for reinforcement of concrete and mortar. Duomix® fibres are synthetic fibres. They reduce cracks during plastic shrinkage.
