摘要
通过试验复配出一种适用于水泥稳定再生集料的缓凝减水剂。结果表明,白糖具有较好的缓凝效果,而木质素磺酸钠兼具减水和缓凝作用;白糖和木质素磺酸钠复配对水泥稳定再生集料的无侧限抗压强度提高效果明显,随水泥掺量增加,高木质素磺酸钠掺量效果更明显。
The purpose of this study is to compound a kind of retarded water reducer which is suitable for the cement stabi- lized recycled aggregate. It found that white sugar has a better retarding effect,while sodium lignosulfonate has both water reduction and retarding effect. The combination of white sugar and sodium lignosulfonate had an obvious effect on increasing the unconfined compressive strength of cement stabiilzed recycled aggregates. With the increase of cement content,the high content of sodium lignosulfonate had better performance on improving the strength.
