Experimental Study on Mechanical Properties and Durability of Fiber-reinforced Concrete
In order to develop a new type of concrete with high strength,crack resistance,and corrosion resistance,this paper takes a high-rise building in Dongying City,Shandong Province as the research background.By employing la-boratory testing methods,different types of fiber materials are incorporated into concrete materials to study the varia-tion laws of mechanical strength and durability of fiber-reinforced concrete.The research results indicate that all three types of fibers enhance the compressive strength,flexural strength,and durability of concrete cubes,with steel fibers showing the greatest improvement.Fibers are beneficial for improving the early flexural strength and long-term com-pressive strength of concrete.Dura fiber concrete and nylon fiber concrete exhibit better durability,while steel fibers do not improve the durability of concrete as much as Dura fiber and nylon fibers.
