Along with economic development and social progress, people have higher and higher requirements on the stress performance of the reinforced concrete beam, and meanwhile, large-scale infrastructure construction has huge requirements on raw materials, so that resources such as river sand and the like are in more and more shortage, the mechanical performance of the reinforced concrete beam is improved on the premise of green conservation, economy and environmental protection, and the resource utilization of the infrastructure construction can be continuously the focus of research of people.
At present, the reinforced concrete beam is reinforced mainly by using high-strength concrete materials, increasing the using amount of reinforcing steel bars and constructing a combined structure, for example, the chinese patent "201721417476.0" discloses a combined reinforced concrete beam, which comprises a concrete main body, bent reinforcing steel bars, stirrups and erection bars. The presence of various reinforcing bars improves the load bearing capacity, stiffness and ductility of the reinforced concrete beam. However, the arrangement of various types of steel bars increases the steel bar consumption and material cost, and increases the construction complexity; for another example, chinese patent "201821938910.4" discloses a reinforced concrete beam reinforcing member, including a concrete slab and a reinforced concrete beam, wherein one or more layers of aluminum alloy reinforcements are disposed in the concrete slab, and the concrete slab is adhered to the bottom of the concrete beam, so that the structural strength is improved, and the reinforced concrete beam reinforcing member has good ductility, fire resistance and corrosion resistance, but the combined structure increases the cross-sectional area of the beam body, is not favorable for fully utilizing space, and is used in a narrow space to affect the beauty; for another example, chinese patent "201811523132.7" discloses a high-strength reinforced concrete beam, which includes a concrete main body and a high-strength steel bar, wherein the concrete main body includes a common concrete layer and a high-toughness fiber-reinforced cement composite layer.
In conclusion, the existing reinforced concrete beam reinforcing method uses a large amount of high-strength materials, is high in cost and is not beneficial to environmental protection and green development; meanwhile, the reinforcing steel bars used in the reinforced concrete beam are difficult to solve the problem of chloride ion corrosion, and the used coarse aggregate and fine aggregate have strict limitation on the content of chloride ions, so that the sustainable utilization of rich resources such as river sand and the like is difficult to realize. Therefore, the reinforced concrete beam member which is environment-friendly, uses green materials and can effectively improve the stress performance has obvious practical significance for the construction of infrastructure.
