%X To offer superior mix proportion scheme for wear resistant concrete, we prepared C60 anti-wear concrete specimens by adding merely or mixed fly ash, slag powder and silica fume, and tested the crack resistance of the specimens using the plane method and the ring method. Research results demonstrate that: 1) when the water-to-binder ratio remains unchanged, the incorporation of fly ash or slag powder reduces the volumetric shrinkage deformation of concrete and prolongs the cracking time of concrete; 2) with the increase of fly ash or slag powder, the effect of restraining concrete cracking tends to be obvious; 3) the incorporation of silica fume evidently promotes the cracking of concrete, and such cracking gets more severe when the amount of silica fume  increases, and the cracking  of concrete tends to be serious; 4) the synergistic complementary effect formed by the fusion of silica fume  and fly ash or slag powder reduces the cracking of C60 anti-wear concrete. The anti-cracking effect is optimal when 15% fly ash and 7% silica fume  are compounded.
