Fortress Concrete Fiber

Fortress Concrete Fiber is used in concrete applications such as slab-on-grade, curbs, driveways, sidewalks, basement floors, garage floors, colored concrete, small precast products, to control plastic shrinkage: anywhere the objective is to control plastic shrinkage cracking while improving basic durability properties.

It ships as a 40 lb box of either 40 one-pound bags or 8 five-pound bags, for control per batch size. Single boxes can be bought online. Pallet pricing and shipping is quoted by SOBX Chemicals.

Dosage

Recommended dosage rate

Recommended standard dosage rate of fiber is 1.0 lb per cubic yard (0.6 kg per cubic meter) of concrete, added directly to the concrete mixing system during, or after, the batching of the other ingredients, and mixed at the time and speed recommended by the mixer manufacturer (usually four to five minutes).

Packaging

Fortress Concrete Fibers are packaged in 1 lb or 5 lb water soluble paper or plastic bags for easy addition to the concrete mixture. The 1 lb bag is the designed mix ratio for use with one cubic yard of concrete cement. The 5 lb bag is the designed mix ratio for use with five cubic yards of concrete cement. The Fibers may be added at any stage of the mixing process, either by hand or machine mix. Be sure to allow enough time for a thoroughly mixed product.
