(57) [Abstract] [Problem] To develop a tile construction method, a waterproof base adjustment material, a pasting mortar, a joint mortar, and a structure that do not cause efflorescence. SOLUTION: The prevention of water intrusion from the front surface and the back surface which causes efflorescence, and when water invades, the amount of free calcium hydroxide which forms the efflorescence is small. The tiled layer is made of a mortar having such a composition as to have a dense and water-tight structure after curing so as to be hard to move. |
