Steel Fiber Reinforced Wet-Mix Shotcrete: Influence of

Date: 6/1/1994. Abstract: Five commercially available steel fibers with different geometries were investigated in wet-mix shotcrete. Concrete mixes were centrally mixed in a batching plant and then transported to the shooting site in ready-mix trucks. After determining the various fresh concrete properties, the mixes were shot on formerly

Fiber Reinforced Concrete Advantages and Disadvantages

Apr 14,  · The right fiber-reinforced concrete can also provide impact-resistance, increase tensile strength and reduce voids in the concrete. A disadvantage of fiber-reinforced concrete is that it can adversely affect workability, especially in the case of steel fiber-reinforced concrete. Even distribution of fibers throughout your concrete is a concern.
