中文摘要：

研究了木质素磺酸盐共聚改性氨基系高效减水剂，合成了不同木质素含量的氨基系减水剂。采用红外光谱表征了改性产物，并对不同木质素含量氨基系减水剂进行ζ电位、净浆流动度、胶砂流动度、泌水率测试，综合分析得出，木质素磺酸盐含量为30％时，可以获得最优性价比的改性产物。

英文摘要：

This paper studies the copolymerization of amino lignosulfonate superplasticizer with different content of lignin. All modification products are represented with infrared spectra and properties such as ζ potential,cement paste fluidity,mortar fluidity, and bleeding rate of amino-based superplastieizer containing various levels of lignin are studied. It is concluded that modified products have the optimal cost performance when the content of lignosulfonate is 30%.
