The failure mechanism of fly ash ceramsite lightweight aggregate concrete under triaxial compression was investigated via conventional triaxial tests at different strength grades and lateral confining pressures. The failure morphology and stress-strain curve of fly ash ceramsite concrete specimens under triaxial compression were analyzed, and the failure mechanism was revealed. The results show that under triaxial compression, the fly ash ceramsite concrete has three failure phenomena as the applied confining pressure increases, i.e., vertical splitting failure, oblique shear failure, and no obvious cracks. There exists a platform flow plastic phenomenon in the full strain curve with the increase of confining pressure. The triaxial compression of fly ash ceramsite concrete can be properly described by an established general formula for the Mohr-Coulomb, octahedral shear stress failure criterion and the Rendulic plane failure criterion.
