PRE-BLENDED DRY CEMENT MORTAR FOR COVERING UNDERGROUND WORKS AND SLOPES.

摘要

The present disclosure is related to a cement mortar that can be used in mining tunnels, designed to be thrown to the walls, shoulders and roofs of underground tunnels in the mining industry for supporting fragmented rocks and/or rock boulders. Among the advantages of this cement mortar, the following should be considered: Safe application in walls, shoulders and roofs of underground mining tunnels; high strength and rigidity improving fragmented rock and rock boulders support, preventing the rock from giving up and therefore also preventing the tunnel from collapsing; resistant to vibrations caused by explosive detonations in underground tunnels; the present invention also can be used in conjunction with electro welded or cyclonic mesh, reinforcing the fragmented rock or rock boulders support.
