<P>PROBLEM TO BE SOLVED: To enhance a grouting effect by providing a material intrinsically having a good flow property with a function of obviating the occurrence of the runaway into the ground and the leakage into a structure without impairing the function of permitting the long distance pressure-feedability of the material and hardly giving rise to bleeding. <P>SOLUTION: The material constituted by effectively utilizing the paper sludge material which is heretofore regarded as industrial waste (hereinafter described as the "PSM") as an additive material for cement bentonite mortar used heretofore is used as a grouting material for the cavity portions, gap portions, etc., of natural ground and as a backfilling material for structures, such as tunnels, headraces in power plants/dams, etc., stone walls, earth retaining walls, substructures, etc. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
