Falling prevention tile and special mortar for laying tile to wall

The invention discloses a falling prevention tile which comprises a glaze face and a laying face. A plurality of grooves are formed in the laying face and are trapezoids, the side length of the lower bottom face of each trapezoid is twice that of the upper bottom face of the trapezoid, both the upper bottom face and the lower bottom face of each trapezoid are squares, and the height of the trapezoids is half the thickness of the falling prevention tile. The falling prevention tile is provided with a steel wire gauze parallel to the laying face, the steel wire gauze is arranged in the half position of the height of the grooves, the distance between every two adjacent steel wires is 0.5-1 cm, meshes of the steel wire gauze are rhombic, and the diameter of the steel wires is 0.05 cm. According to the falling prevention tile, the laying face is provided with the grooves, so that friction force between mortar and the tile is increased; meanwhile, due to the facts that the grooves are trapezoids, and the steel wire gauze parallel to the laying face is arranged in the half position of the height of the grooves, adhesion force between the mortar and the tile can be remarkably increased, and the tile is not prone to falling off; and the grooves are arranged in a clover shape, so that the structure between the tile and the mortar is stable, and the falling possibility of the tile is remarkably reduced.
