Annotation
This research was conducted to evaluate a new type of polycarboxylate superplasticizer. For the synthesis of a polyarboxylate superplasticizer with high water-lowering capacity, polyoxyethylene ether (TPEG) and acrylic acid (AC) were used as monomers, ammonium persulfate as an initiator, and thioglycolic acid (TGC) as a chain transfer agent. The work discussed the influence of additives on the flowability and shrinkage of the concrete cone. The structure of the water-reducing additive based on carbonic acids was described using infrared spectroscopy. The study also assessed the influence of various series of polyhydroxyethylene ether (TPEG)), the amount of acrylic acid (AA), and ammonium persulfate.
