Fiber reinforced concrete: Tailoring composite properties

2018-1-1  Besides the traditional methods of embedding continuous aligned reinforcement in anticipated zones of tensile stress, random discrete fibers can be dispersed into the concrete during the mixing procedure to create a composite material called fiber reinforced concrete (FRC).

Fiber reinforced concrete: Tailoring composite properties

Concrete is one of the most widely used building materials in the world. The single largest limitation of concrete is its weak and brittle nature under tensile stress. In order to improve this material behavior, reinforcement materials that are strong in tension are embedded into the concrete to avoid brittle failure and increase tensile load capacity.

Fiber Reinforced Concrete - an overview ScienceDirect

The ultimate tensile strength of fiber reinforced concrete is calculated by using the following equation: (17) σ t = α 0 × V f × σ f × α b Where, α o is orientation factor and is equal to 0.41, Oh [ 12 ], α b is bond efficiency factor and its value varies from 1 to 1.2 depending upon fiber characteristics, ACI Committee 544 [ 13 ].

Tailoring the Effective Properties of Typha Fiber Reinforced

2022-6-21  The physicochemical properties of natural fiber-reinforced composites rely on the type of fiber, matrix, and matrix-fiber interface. The interface is an in-between zone of fiber-matrix bonds that is present to distribute the stress obtained by the matrix to the fiber (Loh et al. 2013; Ahmad et al. 2015; Cohen et al. 2016).

Fiber Reinforced Concrete Topic

Fiber-reinforced concrete (FRC) is concrete made primarily of hydraulic cements, aggregates, and discrete reinforcing fibers. Fibers suitable for reinforcing concrete have been produced from steel, glass, and organic polymers (synthetic fibers). Naturally occurring asbestos fibers and vegetable fibers, such as sisal and jute, are also used for reinforcement.
