Paper Title:
Separation of Crude Phenols from Bamboo Tar and Modification of Aminobenzenesulfonic-Based Superplasticizer
  Abstract

Aminobenzenesulfonic-based superplasticizer is a kind of high range water reducer synthesized by sodium aminosulfonate, phenol and formaldehyde, as the expensive phenol and the bad workability of concrete added with it, so its application is limited. Bamboo tar is one of the byproducts from bamboo charcoal production, and for its complicated components it isn’t utilized effectively until now. Crude phenols extract was obtained from bamboo tar by using sodium hydroxide solution, and the synthesis of modified aminobenzenesulfonic-based superplasticizer by using crude phenols extract to substitute part of phenol was optimized, and the fluidity of cement paste, compressive strength and water-reducing rate of concrete added superplasticizers were also determined in this paper. The research results indicated that the fluidity of cement paste, concrete compressive strength during the same period, the water-reducing rate and the workability of concrete added with modified aminobenzenesulfonic-based superplasticizer synthesized by using crude phenols extract to substitute 10% phenol were better than that added with aminobenzenesulfonic -based superplasticizer synthesized by only phenol.
