Enhanced Performance of Fracture Strength of Rubberized Concrete Panels by External Reinforcement
In general, producing environmentally friendly concrete is necessary to conserve concrete material resources and reduce construction costs. Recycled tire rubber has been used to produce concrete in various construction works. In the beginning, rubber concrete mixes are done with different percentages of 0%, 6%, 12% and 24% of rubber tires. Then the slump test and the density of the concrete have been tested, in addition to the compressive strength and tensile strength. The strengthening of rubberized concrete slabs with fibre-reinforced polymer sheets is experimentally investigated to increase strength and durability. Thus, in this paper, twelve rubber concrete slabs have been strengthened by FPR sheets with different methods as external reinforcement in order to improve the fracture and shear strength. It is found out that the strengthening rubbered concrete slabs with inclined angles are unnoticeable higher than the straight strengthening configuration. In addition, the type of failure of rubberized concrete panels is affected by the configuration of external reinforcement.
期刊介绍:
The International Review of Civil Engineering (IRECE) is a peer-reviewed journal that publishes original theoretical papers, applied papers, review papers and case studies on all fields of civil engineering. The scope of the Journal encompasses, but is not restricted to the following areas: infrastructure engineering; transportation engineering; structural engineering (buildings innovative structures environmentally responsive structures bridges stadiums commercial and public buildings, transmission towers, television and telecommunication masts, cooling towers, plates and shells, suspension structures, smart structures, nuclear reactors, dams, pressure vessels, pipelines, tunnels and so on); earthquake, hazards, structural dynamics, risks and mitigation engineering; environmental engineering; structure-fluid-soil interaction; wind engineering; fire engineering; multi-scale analysis; constitutive modeling and experimental testing; construction materials; composite materials in engineering structures (use, theoretical analysis and fabrication techniques); novel computational modeling techniques; engineering economics. The Editorial policy is to maintain a reasonable balance between papers regarding different research areas so that the Journal will be useful to all interested scientific groups.
