N2 - Green and highly effective amino-sulfonic acid (AS) water reducing agent was synthesized from p-aminobenzene sulfonic acidbisphenol A and formaldehyde. The influences of the molar ratio of monomers, pH, reaction temperature and reaction time on the performance of the product was studied. The results showed that when n(bisphenol A): n(p-aminobenzene sulfonic acid) = 0.625:1, n (p-aminobenzene sulfonic acid + bisphenol A): n(formaldehyde) = 1:1.2, pH = 10-11, temperature = 90-100°C, and reaction time = 5-6h, the AS water reducing agent had better dispersing ability for cement and concrete particles. In comparison with the conventional amino-sulfonic acid, AS has the characteristics of highly effective water reducing ability, low cost simple preparation process.
