Abstract
As a new type of building material, fiber-reinforced concrete has been widely used in engineering with its unique mechanical properties. This paper summarizes the mechanical properties of fiber-reinforced concrete and its application in engineering. Firstly, the paper introduces the basic concepts and mechanical properties of fiber reinforced concrete, including compression resistance, tensile resistance, crack resistance and durability performance. Through comparative experiment and theoretical analysis, it reveals the influence law of fiber type and mixing amount on the mechanical properties of concrete, which provides a theoretical basis for the optimization design of fiber reinforced concrete in engineering. In terms of engineering application, this paper discusses the practical application of fiber reinforced concrete in bridge engineering, construction engineering, tunnel engineering and water conservancy engineering. In bridge engineering, fiber reinforced concrete effectively improves the bearing capacity and durability of the bridge; in construction engineering, it enhances the crack resistance of floor and wall, and extends the service life of the building; in tunnel engineering, fiber reinforced concrete enhances the seepage resistance and seismic performance of the tunnel; in water conservancy engineering, it improves the erosion resistance and durability of water conservancy facilities. Moreover, this paper also analyzes the technical challenges and future development prospects of fiber-reinforced concrete in engineering application, which provides a valuable reference for related research and engineering practice.
