Results so far |
|
|
| It has been experimentally demonstrated that fiber reinforced fly ash-based geopolymer can exhibit tensile strain-hardening behavior with ultra-high ductility of more than 4 %. The tensile ductility is about 400 times that of normal concrete and multiple crack propagation with tiny crack widths is also observed as in ECC materials. Further improvement in mechanical properties and controlling variability due to fly ash is the next step. |
