ABSTRACT: This study investigated the delayed deformation behaviour of pre-cracked polypropylene fibre
reinforced concrete (PFRC) under sustained loads. Post-peak residual strength, loading-unloading-reloading
response, shrinkage and uniaxial tensile creep are reported. Specimens for the creep test were pre-cracked and
subjected to 30% and 50% stress levels of the post-peak residual strength ...
