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