<p><P>PROBLEM TO BE SOLVED: To provide a grouting material maintaining stable properties even when allowed to stand over a long period after mixing, rapidly hardened after grouting and producing high strength developing properties in a short to a long period in relation to the grouting material used for improving soft ground into strong ground. <P>SOLUTION: The grouting material is characterized as follows. The grouting material is composed of an aqueous slurry A containing 15-50 pts. wt. of 12CaO-7Al<SB>2</SB>O<SB>3</SB>and gypsums and aqueous slurry B containing cement and slag. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
