<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a water sealing material capable of improving strength of the water sealing material to a level of not causing brittle fracture and reducing the variation of image quality while securing deformation follow-up ability of the water sealing material. <P>SOLUTION: In manufacturing a water sealing material M by mixing sediment S, water W, and a solidification material C, the water sealing material M having a uniaxial compressive strength qu of 50 kN/m<SP POS="POST">2</SP>to 200 kN/m<SP POS="POST">2</SP>after cured for 28 days is obtained by mixing the solidification material C of an amount required for making the uniaxial compressive strength qu after cured for 28 days of the water sealing material M to be manufactured 300 kN/m<SP POS="POST">2</SP>to 700 kN/m<SP POS="POST">2</SP>and a development strength suppressing material R consisting of a saccharide or a humic acid. <P>COPYRIGHT: (C)2013,JPO&INPIT |
