Based on the development and application of high-performance FRCC( Fiber Reinforced Cementitious Composite),the effect of different content of fly ash and silica fume on the compressive strength,flexural strength and toughness of high-performance FRCC is studied. The results show that the addition of fly ash and silica fume significantly affects the mechanical properties of high-performance FRCC. The specific optimization content with 50% ash and 15% silica fume can make the flexural strength of high-perfor...
