Description of the Related Art In recent years, as a method of utilizing sewage sludge incineration ash, the sludge incineration ash is press-molded and then fired to form an interlocking block. It is proposed to use it instead in Japanese Patent Laid-Open No. 3-33049. Generally, to lay bricks on soil concrete, sand is laid on soil concrete in an incompletely dried state, bricks are laid on it, and joints are filled with sand or cement. In this method, free substances such as calcium from soil concrete are converted into C in the air.
Reacts with O 2 to produce a white flower phenomenon on the brick surface. Since this white flower phenomenon impairs aesthetics, white flower substances (CaCO 3 etc.) are removed by washing with water or chemical treatment.

的とする。By the way, when a sewage sludge incineration ash firing block is used instead of the brick, the white bloom phenomenon is remarkable, and even if the removal treatment is performed, the third white bloom phenomenon occurs again. There was a problem. As a result of various studies on the above problems, the present inventors found that in the composition of the sewage sludge incineration ash firing block, CaO: 1
It contains 0 to 35 wt% and has a large amount of white sinter component compared to commercial bricks, and a significant white sinter phenomenon occurs due to the additive action of this component and the liberated substance from the soil concrete. When it occurs, the removal treatment results in the addition of water, and it has been found that this induces the white flower phenomenon from the sewage sludge incineration ash firing block itself. Therefore, it is an object of the present invention to provide a method for laying a sewage sludge incineration ash firing block that can greatly reduce the white flower phenomenon by applying simple means.

い。An embodiment of the present invention will be described below with reference to the drawings. First, the soil concrete 1 is cast, then cured and dried, and then the waterproof layer 2 is formed on the surface by, for example, laying a vinyl sheet, waterproof paint, waterproof spray or the like. After that, on the surface of the waterproof layer 2, river sand or sea sand 3 from which salt and free calcium causing caustic phenomenon are removed in advance is laid, and a sewage sludge incineration ash firing block 4 is laid on it. However, the joint portion is filled with river sand or cement 5.
The sewage sludge incineration ash firing block 4 is preferably immersed in water, for example, for 24 hours in advance to remove free calcium components and the like contained in the block itself.

It is possible to reduce the occurrence of and improve the aesthetics. It is also preferable from the viewpoint of hygiene because it can prevent the occurrence of mold secondary to the white flower phenomenon.
