Preparation, Characterization and Performances of Powdered Polycarboxylate Superplasticizer with Bulk Polymerization
A polycarboxylate superplasticizer (PCE) was synthesized in a non-solvent system with bulk polymerization and then was pulverized into powdered form to achieve a rapid transportation and convenient preparation. PCE synthesized by using isopentenyl polyethylene glycol (TPEG) or isobutenyl polyethylene glycol (IPEG) as a macromonomer exhibited the best fluidities and retaining properties at 80 °C...
متن کاملPerformance of Concrete Made with Superplasticizer from Modified Black Liquor and Polycarboxylate
A new kind of retarding polycarboxylate superplasticizer (M20S80) was prepared through the modification of black liquor and polycarboxylate superplasticizer (S) through an Fe-H2O2 reaction system. The synthesis process of M20S80 was introduced. Infrared spectrum analysis (FT-IR) was used to investigate the changes in functional groups in M20S80. At the same time, a mixture of LM20S80 was made b...
متن کاملPreparation and characterization of fine powdered whole soybean curd
PURPOSE Efficacy and comparative characteristics of fine powdered whole soybean curd. METHODS Ground dried soybean to a fine powder (700 mesh) containing bean components in its entirety, and then produced whole soybean curd. Analysed its nutritive components, bioactive substances, antioxidant activities and texture compared with pressed soybean curd. RESULTS Compared with pressed soybean cu...
متن کاملPreparation and characterization of new Ca–Al–polycarboxylate layered double hydroxides
The synthesis and characterization of composite materials based on calcium–aluminum layered double hydroxides (Ca–Al-LDHs), intercalated with organic polycarboxylate (PC) polymers, is described. The PC polymers, which exhibit a “comb-like” architecture, contain ethylene oxide side chains of different lengths. They are intercalated between the cationic Ca–Al–OH-layers when tricalcium aluminate i...
