performance of concrete beams reinforced with basalt fibre

Impact of chopped basalt fibres on the mechanical proper

The concrete used in this research was normal strength concrete with a target compressive strength of 30/37 MPa. In this re-search, fibre reinforced concrete samples were produced using basalt chopped fibres of two quantities (4 kg/m3 and 8 kg/m3) and three different fibre lengths, namely 25.4-mm, 12.7-mm, and 6.4-mm.

Wrapping it Up| Concrete Construction Magazine

Carbon fiber has very high tensile strength and is also very lightweight. When bonded to the exterior of a concrete column, beam, or slab, it can add significant strength without adding weight that would increase the load on foundations and other structural members. The composite material is called fiber-reinforced plastic (FRP).
