Abstract

Isopentenyl polyglycol ether (TPEG-3000), acrylic acid (AA), and slow-release functional monomers (polyacrylates) are the main synthetic monomers, under the sodium hypophosphite-ammonium persulfate redox initiation system, A slowrelease polycarboxylic acid water reducing agent can be synthesized at a reaction temperature of 63°C. This article discusses the effect of the slow-release functional monomer (polyacrylate) on the molecular weight of the slow-release polycarboxylate water-reducer, the fluidity of the paste, and the performance of concrete. The results show that the addition of a slow-release functional monomer will reduce the initial dispersibility of the polycarboxylic acid waterreducing agent, but it will improve the slump retention of the polycarboxylic acid water-reducing agent. Among them, M-3 concrete has almost no loss in slump and expansion within 1h.
