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。
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%.
