Abstract
Water-soluble sodium sulfanilate-phenol-formaldehyde condensate (SSPF) is s ynthesized with a simple synthetic process. The surface activity of SSPF an d its performance in concrete was investigated. It was found that the synth esized SSPF has an advantage over conventional superplasticizers, such as s ulfonated naphthalene formaldehyde condensate (SNF) and sulfonated melamine formaldehyde condensate (SMF), and is more suitable to prepare pumping con crete and self-compacting concrete.
