EFFECT OF THE SYNTHESIS TEMPERATURE OF POLYCARBOXYLATE-BASED SUPERPLASTICIZER ON THE PERFORMANCE OF CONCRETE
Abstract
Good
quality Polycarboxylate superplasticizers (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 (TPEG), Thioglycolic Acid (TGA) and Acrylic Acid (AA), in
the presence of initiator and chain transfer agent according to molecular
structure design principle in different initiatory temperatures (40 and 60 oC).
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 (FTIR) was used for structural characterization.
