The future battlefield environment puts forward higher requirements for the construction of protective engineering. Building materials are the important factors that affecting the comprehensive protective ability of protective engineering. As the main material of protective engineering construction, traditional silicate concrete has the characteristics of brittleness, low tensile strength, poor impact resistance, easy cracking and function. It is difficult to meet the requirements of the actual battlefield environment for the construction of protection projects. Fiber concretes have been widely used in civil engineering and protection engineering because of their good performance. The development history, classification and performance of fiber reinforced concrete are introduced. The research status of mechanical properties, durability, absorbing property and high temperature resistance of fiber reinforced concrete are expounded with the application background of protection engineering. The development trend of fiber reinforced concrete is analyzed in order to provide reference for the research and application of new materials for protection engineering.
