Process for fixing tiles in position

A process for fixing in position on a cement mortar coated supporting structure wear-resistant lining tiles of ceramic, fused mineral and metallic material for highly abrasive bulk material such as coal ores and rock, said process comprising:

• cleaning the back side to be coated of each of said tiles,
• applying an epoxy-containing coating to the cleaned back side of said tiles, said epoxy-containing coating having a thickness of 1.5-2 mm and consisting of a resin mixture and a curing agent mixed at a ratio of 100 to 17, the curing temperature for said epoxy-containing coating being in the range of 290-310 K..degree.,
• the resin mixture consisting of
• 36.9 parts by weight epoxy resin,
• 25.2 parts by weight of fine sand,
• 34.9 parts by weight of quartz sand powder,
• 1.0 parts by weight of thixotropic agent, and
• 2.0 parts by weight of conducting carbon stock,
• dusting and rolling in the epoxy-containing coated back side of said tiles a layer of material having an affinity for cement mortar, the material being selected from the group consisting of quartz sand, lavalite and broken expanded clay, with a grain size of 1-3 mm,
• said material being rolled into the epoxy-containing coated back side of said tiles at a pressure of 1 to 2 N/square mm, and
• following the rolling in of said material, hardening said epoxy-containing coating, placing and fixing in position said coated tiles on the cement mortar coated supporting structure and filling up the spaces between said tiles by a pointing compound, so as to produce a high shear strength in said tiles.
