HIGH-STRENGTH GROUT COMPOSITION AND HIGH-STRENGTH GROUT MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a high-strength grout composition and a high strength-grout material which are easy to be kneaded and mixed, have a small dripping amount after filling while having high initial flowability after kneaded and mixed, and can obtain a high compressive strength.;SOLUTION: A high-strength grout composition which contains a thickener that is not crosslinked with cement, an amorphous aluminosilicate mineral powder, gypsum, a water-reducing agent, and a hydroxyl group and has a viscosity of 2 mass% concentration of less than 1,000 mPa s, and a thickener that is crosslinked with a part of the hydroxyl group and has a viscosity of 2 mass% concentration at 20°C of 1,000-5,000 mPa s.;SELECTED DRAWING: None;COPYRIGHT: (C)2017,JPO&INPIT
