【摘要】 文章介绍了国内外膨胀剂的发展状况和钢渣利用情况，提出把钢渣掺入水泥中作膨胀剂的设想并进行了一系列实验。结果表明，用钢渣做膨胀剂，膨胀龄期较长，膨胀状况良好。水泥抗压强度随钢渣掺量的增加而有所降低，水泥安定性合格。更多还原

【Abstract】 This article introduces the development status of expansion agent home and abroad and the utilization of blast furnace slag, and proposes the idea to mix blast furnace slag into cement as expansion agent, and a series of experiment have been complete. The results show that a longer expansion period and a better expansion could be achieved with the blast furnace slag as expansion agent. The compressive strength of cement is somewhat reduced with the increase of the slag quantity mixed, however, the soundness remains qualified.更多还原
