Experimental Materials.
Then the materials were mixed and divided, and each sample weight is 500 g used for particle size analysis and grinding experiments.
Grinding kinetic refers to the relationship between grinding rate and grinding time of the ground material.

The test material and mixing ratio Test material.
Coarse aggregate: The lytag which is produced in Baotou Jingzheng building materials company.
Material is modified polypropylene, and the fiber length is 38 mm.
In order to avoid the interference with the mechanical properties of lightweight aggregate concrete and the fiber enhanced rule which is caused by admixture and mineral powder, this test is not mixed with admixture and mineral powder materials.

Experimental Materials and specimens.
The fatigue tests on metallic materials suggest that the fatigue crack initiation of circular notched CT specimen at lower load belongs to high cycle fatigue, which is controlled by a stress field, and the plastic deformation at crack tip is small.
