Novel acid-based geopolymer synthesized from nanosized tubular halloysite: The role of precalcination temperature and phosphoric acid concentration

Halloysite is a hydrated polymorph of kaolinite but possesses a distinctive nanosized tubular structure and surface reactivity. The microstructure and mechanical performance of geopolymers derived from calcined halloysite via acid-activation were investigated in this study. The acid-activation products were characterized using a combinati...More
