竹浆黑液氧化-磺甲基化制备混凝土减水剂研究
Preparation of Concrete Water-reducer by Oxidation and Sulfomethylation of Bamboo Pulping Black Liquor
摘要
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 work shows great significance in pollution prevention and the reuse of black liquor.关键词
