Behaviors of Glass Firer in Pavement under Compression and Flexural Stresses

Abstract

Concrete is weak in tension and has a brittle character. The concept of using fibers to improve the characteristics of construction materials is very old. Early applications include addition of straw to mud bricks, horse hair to reinforce plaster and asbestos to reinforce property. The modern development of fiber reinforced concrete (FRC) started in the early sixties. Addition of fibers to concrete makes it a homogeneous and isotropic material. When concrete cracks, the randomly oriented fibers start functioning, arrest crack formation and propagation, and thus improve strength and ductility.

The objective of this study is to investigate the effects on stress development in pavement and on critical design factors from substituting GFRP reinforcement for conventional steel reinforcement in pavements to determine the performance characteristics of the GFRP-reinforced concrete pavements. The results of this study target the design of pavement with GFRP rebar as an applicable reinforcement and propose feasible GFRP designs to be constructed.

The glass fibers reinforce the concrete, much as steel reinforcing does in conventional concrete. The glass fiber reinforcement results in a product with much higher flexural and tensile strengths than normal concrete, allowing its use in thin-wall casting applications. GFRC is a lightweight, durable material that can be cast into nearly unlimited shapes, colors and textures

GFRC is a specialized form of concrete with many applications. It can be effectively used to create façade wall panels, fireplace surrounds, vanity tops and concrete countertops due to its unique properties and tensile strength. One of the best ways to truly understand the benefits of GFRC is a unique compound.
