Aug 19, 2019 · Both steel and synthetic fibre reinforcement is also increasingly common for shotcrete, or sprayed concrete mixes, an application that’s finding broader use both in tunnelling projects and beyond. THE NEXT WAVE Meanwhile, many additive firms are experimenting with combining separate admixtures and fibres to form hybrid solutions.
For determining tensile fracture properties of concrete and fibre-reinforced concrete, the three-point bending test on a notched beam is probably the most widespread method; see RILEM TC-50 FMC (1985) for plain concrete and RILEM TC 162-TDF (2002b) for steel fibre-reinforced concrete.
Concrete is relatively weak in tension and may require some form of reinforcement to cope with tensile forces. Steel reinforcing bar is often used to cater for tensile and compressive forces. However, current research shows that the use of steel reinforcing bar does not afford concrete protection against impact.

Jul 06, 2004 · Polyolefin materials, such as polypropylene and polyethylene, have been used for reinforcing concrete and offer an economic advantage due to relative lower cost of the material. However, these polyolefinic materials, being hydrophobic in nature, resist the aqueous environment of wet concrete.
The resulting combination of materials is known as a composite. A composite material is made from two or more components, generally a low modulus, low strength material (e.g. a thermosetting resin, a thermoplastic resin, an elastomer) and a high strength, high stiffness reinforcing-fibre material (e.g. glass, carbon, Kevlar).
