| Abstract: | Lignosulfonate was prepared as water-reducer via oxidation and sulfomethylation of bamboo alkaline-pulping black liquor.Results indicated that the water-solubility and surfactivity of lignin in black liquor can be effectively improved through the modification.The prepared lignosulfonate can be employed as a cost-effectively water-reducer in concrete industry,since it can reduce cement slurry viscosity so as to increase the fluidity by means of dispersing cement slurry floc and releasing the bound water.This... |
| Keywords: | black liquor sulfomethylation concrete water-reducer fluidity |
