Fracture properties of cement and alkali activated fly ash based concrete with application to segmental tunnel lining
Cement and alkali activated fly ash based concrete is analyzed. Fracture properties of various compositions are investigated both experimentally and numerically. Primary attention is accorded to the influence of the amount of fly ash replacing cement on fracture energy. The influence of short synthetic fibers on mechanical properties is also studied. Artificial neural network is introduced to provide parameters of the constitutive model.
