Abstract
A water-soluble sulphonated phenolic resin (SPF) was synthesized from pheno l, formaldehyde and sodium bisulfite through a four-step reaction. The synt hesized SPF could reduce the water content, improve the workability and com pressive strength of concrete. The best results were obtained for concrete containing 2 wt% SPF, which are comparable with commercial superplasticizer s. Thus, SPF has the potential to be used as a superplasticizer.
