Effects Of Roof Bolt Pressure On Properties Of Short Fiber And Rubber Composite Material

摘要

Roof bolt pressure is one of the important factors which impacts the mixing process and roof bolt pressure of SFRC greatly. The effects of different roof bolt pressure on mixing process of SFRC have been researched by experiments. In the paper, the roof bolt pressure was changed from 0.3MPa to 0.6MPa respectively. And also the addition of short fibers was about 0phr~6phr. The experimental results indicated that SFRC had better physical and mechanical properties as roof bolt pressure was about 0.6MPa, and the addition of short fibers was about 3phr.
