Fibres are generally used as resistance of cracking and strengthening of concrete. In this project, I am going to carry out test on steel fibre reinforced concrete to check the influence of fibres on flexural strength of concrete. According to various research papers, it has been found that steel fibres give the maximum strength in comparison to glass and polypropylene fibres. Hence, in this pr...

Combining different fiber types may improve the mechanical properties of reinforced concrete. The present study is focused on investigating hybrid concrete (HFRC) with steel and basalt fiber. Mechanical fine-grained are investigated. results demonstrate that using optimal reinforcement ratios avoids mixtures’ segregation improves their homogeneity. Concrete has higher strength. Effective method...

This paper introduces an innovative concept of FRP/concrete hybrid structural member. This concept includes rectangular filament-wound glass fiber reinforced polymer (GFRP) tubes, totally or partially filled with concrete, and used as beams and/or columns. The paper presents the experimental program and results of three beams and five short columns tested with different eccentricities. Two of t...

Ductile fiber-reinforced cement-based composites (DFRCCs) are being investigated for new design as well as retrofitting of structures in seismic regions. DFRCC is highly ductile and is characterized by strain-hardening in tension to strains over 3% and by unique cyclic loading behavior. To accurately predict the structural performance of DFRCC components under cyclic and seismic loading, a robu...

This study concerns improvement of flexural stiffness/strength of concrete members reinforced with externally bonded, aluminum-glass fiber composite (AGC) beams. An experimental program, consisting of seven reinforced concrete slabs and seven reinforced concrete beams strengthened in flexure with AGC beams, was initiated under four-point bending in order to evaluate three parameters: the cross-...

Objective: Introduction of fiber-reinforced composites (FRC) greatly enhanced the restoration of fractured anterior teeth. The purpose of this study was to assess the effect of fiber reinforcement on fracture resistance of incisal edge composite restorations of variable thicknesses. Methods: Forty extracted sound human maxillary incisors were divided into four groups of 10. Incisal reduction wa...

There is a growing need for the rehabilitation, repair, and upgrading of concrete structures such as bridges and buildings. The repair or rehabilitation of reinforced concrete structures often offers a lower cost alternative to rebuilding, and it is traditionally achieved by bonding steel plates to the tensile face of a reinforced concrete member. The shear strength can be enhanced with plates ...
