STUDY OF PERFORMANCE OF HIGH SLUMP LOSS OF RESISTANCE OF POLYCARBOXYLATE SUPERPLASTICIZERS ON SELF-COMPACTING CONCRETE

摘要：

　　A new kind of polycarboxylate superplasticizer with high slump loss resistance was obtained by designing scheduled molecular structure.The number average molecular mass of the polymer was characterized by the gel permeation chromatography (GPC) measurements.And chemical structure of the polymer was observed by the Fourier Transform Infrared Spectroscopy (FT-IR).The results showed that the good workability maintaining of SCC could be achieved through direct adjustment of number average molecular mass and different unsaturated monomer in synthetic process.The FT-IR analysis illustrated that the high slump loss resistance of polycarboxylate superplasticizers with ether and expectations of molecular structure were designed.
