A Study on the Performance of Lignin-Modified Amino-Based Superplasticizers

摘要：

In this study, amino-based superplasticizers modified by copolymerization of lignosulfonate are studied and amino-based superplasticizers containing various levels of lignin are synthesized. 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 superplasticizers containing various levels of lignin are studied. Comprehensive analysis reveals that modified products have the optimal cost performance when the content of lignosulfonate is 30％(wt).
