Synthesis and performance of hydrophobically modified polycarboxylate type superplasticizer

Synthesis and performance of a hydrophobically modified polycarboxylate-type superplasticizer is investigated. For this purpose alkoxy polyethylene glycol mono acrylic acid was synthesized by esterification. Moreover the reaction condition was optimized and characterization was performed by FTIR. Afterward, the esterified product was polymerized and then neutralized to achieve a new polycarboxylate-type superplasticizer. The performance of superplasticizers was evaluated by slump test. Additionally, the density of macromonomer on the performance of superplasticizer was investigated to optimize formulation. According to the results, all synthesized polymers could be applied as superplastisizer
