Description

Technical Field

[0002] In the design of modern tunnel lining structures, permanent linings based on shotcrete have high requirements for shotcrete quality and process. In different natural and engineering environments, shotcrete in tunnels has a high rebound rate and even a large amount of falling due to the influence of material composition, concrete and surrounding rock conditions, construction equipment and process, and construction quality control methods.

[0003] By adjusting the composition of shotcrete materials, introducing silica fume, steel fiber, organic fiber and other functional materials into shotcrete, the rebound rate of shotcrete can be improved and the various properties of shotcrete can be improved.
