Microstructure and mechanical properties of carbon microfiber reinforced geopolymers at elevated temperatures

The present work deals with the effect of carbon microfiber addition on the development of microstructure and mechanical properties of geopolymers at elevated temperature. The carbon microfibers were prepared from recycled inexpensive carbon fibrous wastes by ball milling, and then subsequently incorporated under 5, 10 and 15 wt% loading into metakaoline based geopolymers. The addition of carbon microfibers was found to produce compact structure...
