Effects of sulphonated phenolic resins on the properties of concrete

Chen, S.D. / Hwang, C.H. / Hsu, K.C.

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