- Abstract
A new kind of Naphthalene Formaldehyde Superplasticizer (M20N80) was prepared through the modification of black liquor and Naphthalene Formaldehyde Superplasticizer (N) through an Fe2+-H2O2 reaction system. The synthesis process and synthesis mechanism of M20N80 was introduced. Infrared spectrum analysis (FT-IR) was used to investigate the changes in functional groups in M20N80. In comparison with N and LM20N80, the influences of M20N80 on the properties of concrete were studied. The results indicate that M20N80 had a better water reduction rate in concrete than LM20N80 and was close to N under the same conditions. Furthermore, M20N80and N had almost the same effect on compressive strength development of concrete. Finally, M20N80 appeared to be more effective in improving the pore structure of concrete.
