摘要：
The types and the structures of the reaction products of alkali-activated carbonates cementitious material were investigated by means of X-ray photoelectron spectroscopy for element quantitative analysis, infrared spectroscopy, X-ray diffraction and 29Si nuclear magnetic resonance. Results show that the products of the reaction of carbonates powder with modified water-glass are gel-like substances, which are mostly comprised of magnesium silicate gel of chrysolite type, hydration calcium silicate of gyrolite type and a certain amount of silica gel as well.
