Creep properties of geopolymer cemented coal gangue-fly ash backfill under dynamic disturbance
Construction and Building Materials（2018）
Abstract
•Creep disturbance testing machine was developed and used to test GCGFB.•Dynamic disturbances accelerate the creep process of GCGFB.•GCGFB presents impact softening and hardening at high and low disturbance energies, respectively.•New creep disturbance constitutive model established for GCGFB.
