Abstract:
In this study, the interaction between a calcined clay and novel, self-synthesized amphoteric superplasticizers was investigated. For this purpose, a natural occurring mixed layer clay was calcined at 750 °C in an industrial-scale rotary kiln and its particle size, chemical and mineralogical composition and electrokinetic behavior were determined. Specific amphoteric MPEG type polycarboxylate (PCE) copolymers holding carboxylate as well as quaternary ammonium functionalities were synthesized and... »
