Industrial Concrete Floor

Industrial flooring is often subject to high levels of wear and tear, making it necessary to use materials that can withstand these conditions. One option is to use steel fiber reinforcement in the flooring. This type of reinforcement can provide increased strength and durability, making it ideal for use in industrial settings.

Tunnel Shotcrete

Steel fiber use in tunnel shotcrete support has been increasing over the past 40 years. The primary purpose of steel fibers in shotcrete is to improve toughness and flexural strength. They are now also used to improve abrasion resistance, shrinkage cracking, and to control subsurface water ingress. In the United States,tunnel shotcrete reinforcement is specified in ACI 506R and generally used according to the recommendations of ACI Committee 506. These specifications are currently under revision to reflect the most recent trends in fiber reinforcement.

There are three major fiber types used for tunnel shotcrete reinforcement:

1) Deformed bars

2) Discrete (bundled) fibers

3) Manufactured (monofilament) fibers

1) Deformed Bars

Deformed bars are the most common type of steel reinforcement used for tunnel shotcrete reinforcement. The bars have a ribbed or deformed surface to increase the bond strength between the bar and concrete. The typical bar size used for tunnel shotcrete reinforcement is 3/8-inch diameter. Bar diameters less than 3/8-inch are not commonly used due to difficulties in cutting the bars to length. The concrete cover over the bars is also an important factor in determining the amount of reinforcement
