Title:
INORGANIC POWDER AND HARDENABLE INORGANIC COMPOSITION
Document Type and Number:
Japanese Patent JPH10158007
Kind Code:
A
Abstract:
To obtain inorg. powder having high reactivity to an aq. soln. of an alkali, especially an alkali metallic silicate and to obtain a hardenable inorg. compsn. excellent in hardenability and capable of giving an inorg. hardened body excellent in strength and water resistance.
The objective inorg. powder is inorg. Al1O3-SiO2 powder contg. Si having a peak at -80 to -105ppm in a 29Si-NMR method. The Al2O3-SiO2 powder has ≥0.4° half-width of a peak (FWHM) in a powder X-ray diffraction method. The objective hardeneable inorg. compsn. consists of the inorg. Al2O3- SiO2 powder, an alkali metallic silicate and water.
