摘　　要：试验研究水玻璃激发剂用量、矿渣种类和养护方式对矿渣碱激发的影响和三种发泡剂的发泡性能。研究表明,水玻璃(模数1.3、浓度48%)用量为矿渣的18wt%时激发效果最好,矿渣越细激发效果越好,矿渣碱激发后宜采用湿养护;不同发泡剂具有显著不同的发泡性能。以Km-12发泡剂试制了不同干密度(0.4～0.7)g/cm3的碱-矿渣泡沫混凝土,其强度远大于同密度等级的硅酸盐水泥泡沫混凝土。Influence of the content of water glass activator,slag types and curing modes on slag alkali-excitation and foaming performance of three types of foaming agents were researched experimentally.It has been shown that the excitation effect is best when the content of water glass activator 18%(by mass of slag),the finer slag ground the excitation effect better,curing mode after activated by alkali should adopt wet-curing,and different foaming agent has significant different foaming performance.Alkali-slag foam concrete with different dry density(0.4 ～ 0.7 g / cm3) has been produced by Km-12 foaming agent,and its strength is much higher than the same density Portland cement foam concrete.
