| Abstract |
In this paper, the reaction mechanism of glassy waste in both single-glass and glass-Ca(OH)(2) systems was investigated. However, while adding Ca2+ or Al3+ ions into reaction solutions, the ions interacted with the Si-rich hydrated layer on the surface of glass particles and produced zeolite or anorthite crystals between glass particles. As for glass-Ca(OH)(2) system, besides facilitating the formation of crystals between glass particles, additional Ca2+ or Al3+ ions also promoted the growth of tobermorite or xonotlite crystals at the glass-Ca(OH)(2) interface. In conclusion, the strength of materials was greatly enhanced by strengthening crystal connections in glass particles and at the glass-Ca(OH)(2) interface. |
