When is the best time to add FORTA synthetic fibers to the concrete?
FORTA products should be added to the concrete mixing system at the batch plant for best distribution. Follow the normal mixer manufacturers’ standard recommendations and ASTM C-94. Mixing time should be a minimum of four to five minutes per load at a normal mixing speed. The batch plant will be the most economical and safest place for addition of the fibers. Typically it is not recommended that fibers be introduced to the mixer as a first ingredient, but added with other ingredients or at the end of the addition sequence. Contact FORTA for mixing and addition recommendations for specific types of mixing equipment.
