| Abstract: | The main factors affecting the anti crack performance of concrete are analyzed, which include concrete strength, elastic modulus, creep, linear expansion coefficient, hydration temperature rise, volumetric deformation, and so on. The index of anti crack deformation, which is the ratio of loading deformation of concrete and volumetric deformation, is used as the relative index to assess the anti crack performance of various artificial aggregates. |

| Keywords: | concrete anti crack performance aggregates deformation index |
