How to use Steel Fiber in concrete? – FORCETECH

Steel fiber in concrete represents only one part of the system. There are other important elements to consider, including subgrade preparation, concrete mix design, and the total water in a mix. The condition of the subbase is critical. The subgrade under a slab must have adequate drainage, be properly compacted, and have a flat, smooth surface.
