Production method of impervious material

摘要

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.;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/m² to 200 kN/m² 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/m² to 700 kN/m² and a development strength suppressing material R consisting of a saccharide or a humic acid.;COPYRIGHT: (C)2013,JPO&INPIT
