PROBLEM TO BE SOLVED: To prevent a lightweight aggregate from appearing, and in addition, a fresh concrete from scattering underwater. ;SOLUTION: In this method for placing underwater lightweight concrete, a fluidity covering layer 3 formed of a material lighter than underwater non- separable lightweight concrete 5 is placed before placing the underwater non- separable lightweight concrete. Then, the underwater non-separable lightweight concrete 5 is placed in or below the fluidity covering layer 3.;COPYRIGHT: (C)2001,JPO
