摘　　要：研究了从精苯焦油废液中提取水泥减水剂的工艺过程．系统地分析了提取产品的各项物性指标．应用试验表明．对水泥的减水率达２０％．同时水泥的抗折强度和抗压强度均有所提高．由此可以看出该提取物是一种优良的水泥减水剂．This paper studies the technology of drawing water reducer from acid-tar that is produced in the process of refining benzene. All kinds of physical chemistry qualities on the product are examined completely. Result of 20% water reducer rate has been proved in the experi- ment. Meanwhile,the rupture strength and the compressive strength of cement are increased. This product is the excellent water reducer of cement.
