Glass is widely used in our lives through manufactured products such as sheet glass, bottles, glassware, and vacuum tubing. Glass is an ideal material for recycling. The use of recycled glass helps in energy saving. The increasing awareness of glass recycling speeds up inspections on the use of waste glass with different forms in various fields. One of its significant contributions is to the co...

1. Abstract Natural fibers are being increasingly used to substitute artificial glass and carbon fibers in polymer composites. It is important to know how the mechanical properties of these natural fiber composites compare with those of the traditional glass and carbon fiber composites. Glass and carbon fiber composites are currently being used in many applications that may not require such hig...

The availability of information about the physical and mechanical properties fiber-reinforced concrete allows to calculate structures based on it with a proper approximation reality. experimental data elastic modulus first second kind, Poisson's ratio, tensile compressive strength limits for characteristic fiber lengths percentage reinforcement by weight are condition creating an algorithm calc...

As part of a larger project to investigate the use of Fiber-Reinforced Polymer (FRP) materials in bridge construction, a short-span FRP-reinforced concrete bridge was installed in central Missouri. The Walters Street Bridge is a precast concrete panel bridge reinforced with both glass FRP (GFRP) and carbon FRP (CFRP) reinforcing bars. It was designed according to the American Concrete Institute...

In the present research work, the flexural modulus and strength of glass fiber-epoxy resin and carbon fiber-epoxy resin composites have been enhanced through fiber tension during curing of the polymeric resin. This study showed that the tension applied on the fibers increased the flexural modulus of the glass-epoxy composites up to 12% and the flexural strength up to 19%. The flexural modulus a...

Basalt fiber is an eco-friendly and a promising material for the strengthening of reinforced concrete (RC) structures due to its various advantages such as low cost, better resistance chemical attack, good thermal characteristics higher tensile strength than E-glass fiber. However, only few experimental investigations have been reported in literature on RC beams with basalt polymer (BFRP) compo...

A non-destructive measuring technique to determine the fiber content in hardened steel fiber reinforced concrete is presented. The technique is based on an accurate open-ended coaxial probe reflectometry method for measuring the effective permittivity of the fiber reinforced concrete and on a mixing rule from the classical homogenization theory for deriving the fiber content from the measured p...

a r t i c l e i n f o Keywords: Concrete (E) Fiber reinforced concrete (FRC) (E) Constitutive relationship (C) Cohesive fracture (C) Fracture energy (C) A simple, effective, and practical constitutive model for cohesive fracture of fiber reinforced concrete is proposed by differentiating the aggregate bridging zone and the fiber bridging zone. The aggregate bridging zone is related to the total...
