FiberForce 850 is a blend of steel/micro synthetic fibers. FiberForce 850 combines a Type V steel fiber with a monofilament micro fiber. The specific blend ratio is 23 lb/1 lb (steel fiber/micro synthetic fiber) per 24 lb bag. This blended technology is developed for post-first crack reinforcement with enhanced plastic shrinkage/settlement crack control.
FiberForce 850 is packed in pre-weighed degradable bags. FiberForce 850 can be preloaded in empty ready-mix drums or added anytime during or after concrete is batched. Mix for 5 minutes at full charging speed (75-100 revolutions) to ensure complete dispersion of fibers. FiberForce recommends the utilization of the appropriate water reducing chemical admixture for any slump or workability modification that may be required with this technology.
