摘要： PROBLEM TO BE SOLVED: To restrain water absorption of a cement board.
SOLUTION: According to this fixing method, in constructing a structure with the cement board 10 left behind on the outer surface of a structure formed by placing hydraulic material 12 such as concrete or mortar, the cement board 10 is also used as a placing sheathing board for the hydraulic material 12. The cement board 10 is a fiber reinforced cement board composed mainly of cement and reinforced by high-strength vinylon fiber, and it is manufactured by a forming method including a press process. Projecting and recessed parts 14 having a height of 1 mm are formed at intervals of about 1 to 2 mm on the back of the cement board 10. In using the cement board 10 as a permanent form, a water absorption adjusting agent 16 for regulating water absorption of the cement board 10 is previously applied to the whole surface of the back side coming into contact with the hydraulic material 12.
