摘要： Phosphate glass powder is a curing agent for alkaline binders such as water glass or silica sol. The phosphate glass powder may be pre-treated with a substance such as calcium hydroxide that is capable of reacting in solution with a phosphoric acid ion to form an insoluble or scarcely soluble salt, to decrease the reactivity of the powder with the water glass and permit improved control of the pot life of the mixture. The cured compositions have good bonding strength and water resistance.
