Test and Research on Mechanical Property of Ceramsite Steel Fiber Concrete

Destructive process of ceramsite concrete is nominally that at the earliest stage, microcracks appear in ceramsite aggregate and spreading to boundary surface. Once they develop to mortar, if no other factors to restrain crack propagation, ceramsite concrete will be destroyed quickly. After including of steel fiber, toughness of ceramsite concrete will be greatly increased. In the treatise, influences on different amount included of steel fiber in above CL40 ceramsite concrete on compression, pulling, bending strength and bending resistant toughness and compression toughness are tested and researched.
