Abstract: Alkali solution was prepared with NazSiOs, NaOH and Ca(OH)z, then steel slag was activated using alkali solution obtaining zeolite hydrochemical products. The effects of NazSiOs amount, NaOH amount and Ca(OH)2 amount on the compressive strength of the alkali steel slag cementations materials were studied. The optimal compressive strengths of materials were characterized. The results showed that NazSiO, has significant effect on 7 d compressive strength of materials, NaOH had significant effect on 3 d compressive et seae oasaa aaeueseseoan NaOH amount was 4.50 g and Ca(OH)2 amount was 6.75 g, the compressive strength of materials was the best. The addition of alkali solution was beneficial to the formation of zeolite hydrochemical products in the gelation system.
Key words: alkali solution; alkali steel slag; steel slag of cementations materials; compressive strength

前言
水泥生产工业作为传统产业是资源、能源消耗大户
和碳排放大户，特别是我国正处于基础建设的高峰期，水泥产量和需求量巨大且逐年增长112)，我国各种工业固体废弃物年排放量逐年增多，不仅占用土地、污染环
境，同时也是一种巨大的资源浪费，钢渣作为钢铁工业的废渣，其化学成分和矿物组成与水泥熟料相似，若以钢渣粉取代水泥熟料制备钢渣胶凝材料不仅可资源再利用，而且对钢铁工业的可持续发展十分有利，也缓解了国民经济巨大的压力和负担，既有利于节省资源，又有利于环境保护[3-5]
