Document Type and Number:
Japanese Patent JP5052804
Kind Code:
B2
Abstract:
To provide a grout composition which is excellent in fluidity, compensates the settling or shrinkage of unhardened mortar or concrete and is excellent in initial strength development and dimensional stability even in a cold season of around 5°C and to provide mortar or concrete and a grout material using the mortar or concrete.
The grout composition (1) contains: a hydraulic material containing a 3Ca-SiO2solid solution, 11CaO-7Al2O3-CaF2and anhydrous gypsum; a quick hardening material containing calcium aluminosilicate glass and anhydrous gypsum; fine powder of blast furnace granulated slag; silica fume; calcium hydroxide; alkali metal aluminate; a high-performance water reducing agent; and a setting modifier. The grout composition (2) is the grout composition (1), containing a polycarboxylic acid-based high-performance water reducing agent and a melamine-based high-performance water reducing agent as the high-performance water reducing agent. The grout composition (3) is the grout composition (1) or the grout composition (2), containing calcium nitrite and/or calcium nitrate. Mortar or concrete is obtained by blending the grout composition, water and aggregate.
