Mixing

Most fibers today are added at the ready-mix plant. The most popular method is to use a conveyor to load them into the truck just after the concrete ingredients are loaded. If they are mixed into concrete on a jobsite, either conveyors or machines that can blow them into the mixer are used. Either way, mixing is easily accomplished.

Can you recycle steel fiber concrete?

“Not easily” is the answer most heard. Carter says anything above 50 pounds of fiber per yard of concrete has to be sawed and lifted out. “You won’t get it out with a jackhammer.” McPhee agrees, “If you forgot to run a waterline under a slab you have to saw the lines of the trench completely through the concrete and then cut the concrete into manageable sections that can be lifted out.”

No person interviewed for this article knew the best way to demolish a slab because they didn’t know of anyone who has done it. Even early applications of steel fiber reinforced concrete continue to perform well and that speaks well for the product.
