Abstract :Good quality Polycarboxylate superplasticizers insert ignore into journalissuearticles values(PCEs); production is increasingly important due to development of the construction industry in the world.  In this study, modified PCEs were synthesized via free-radical polymerization of   Translated Polyethylene Glycol insert ignore into journalissuearticles values(TPEG);, Thioglycolic Acid insert ignore into journalissuearticles values(TGA); and Acrylic Acid insert ignore into journalissuearticles values(AA);, in the presence of initiator and chain transfer agent according to molecular structure design principle in different initiatory temperatures insert ignore into journalissuearticles values(40 and 60 o C);. The effects of PCEs synthesized at different temperatures on the concrete such as water cutting, workability and compressive strength of 7 and 28 days’ have been examined.  Fourier transform infrared spectroscopy insert ignore into journalissuearticles values(FTIR); was used for structural characterization.
