the present paper offers a meso-scale numerical model to investigate the effects of random distribution of aggregate particles and steel fibers on the elastic modulus of steel fiber reinforced concrete (sfrc). meso-scale model distinctively models coarse aggregate, cementitious mortar, and interfacial transition zone (itz) between aggregate, mortar, and steel fibers with their respective materi...

The usefulness of fiber reinforced concrete (FRC) in various civil engineering applications is indisputable. Fiber reinforced concrete has so far been successfully used in slabs on grade, shotcrete, architectural panels, precast products, offshore structures, structures in seismic regions, thin and thick repairs, crash barriers, footings, hydraulic structures and many other applications. This p...

This study investigated the influence of nanoclay on the impact damage resistance of glass fiber-epoxy composites under high velocity ice impact loading. Addition of 0.5 wt. % nanoclay into epoxy was shown to improve damage resistance compared to composite plates having no nanoclay platelet. The glass fiber-epoxy composites containing nanoclay brought about substantial improvement in ice impact...

This is a comparatively recent advancement in construction technology. saves money the process because it light weight. The use of glass fiber to replace steel reinforced concrete structures helps reduce corrosion and structural damage. Many alternatives have been investigated increase concrete’s strength, durability, shrinkage characteristics, serviceability while considering global environmen...

There is an increased use of fiber reinforced polymer composites (FRPC) in a wide area of engineering fields for various reasons including, ease of transportation and installation, high strength to weight ratio and favorable durability in different conditions. On the other hand, the use of this material as confining shells has been an interesting matter for retrofit, strengthening and construct...

Several types of fibers have enhanced the structural response reinforced concrete-filled steel tubes (CFSTs). This article presents a state-of-the-art review studies done on axial compressive behavior and glass fiber-reinforced CFSTs. The aim using is to improve research indicates findings experimental programs analytical evaluations effects fiber incorporation results this work demonstrate tha...

The applicability of acoustic emission (AE) techniques to monitor the mechanism of evolution of polyvinyl alcohol (PVA) fiber concrete damage under temperature fatigue loading is investigated. Using the temperature fatigue test, real-time AE monitoring data of PVA fiber concrete is achieved. Based on the AE signal characteristics of the whole test process and comparison of AE signals of PVA fib...

The use of fabrics in the form grids embedded cementitious matrices—usually termed as textile-reinforced mortar, fiber-reinforced matrix, or concrete—demonstrate a more stable performance elevated temperature conditions compared with polymers. This study investigated residual tensile properties bare yarns and mortar after exposure to 100 °C, 200 300 °C. Three different coated fabric textiles we...

the current research intends to study the possibility of producing fiber recycled self-compacting concrete (frscc) using demolitions as a coarse aggregate (crushed red brick and crushed ceramic). steel fibers were used in recycled self-compacting concrete (rscc) to improve fresh and hardened properties of this type of concrete. thirty nine concrete mixes were prepared to achieve the aim propose...
