Experimental Study on Deterioration Characteristics of Partially Repaired RC Slabs under Freezing-Thawing and Fatigue Combined Action

摘要

1.Under cold temperature, apparent increase in slab stiffness undernegative temperature improved fatigue durability and extendedfatigue life of RC slabs.2.Using low durable materials against frozen environment to upperrepair decreased slab thickness earlier and resulted in bringingsmaller repair effect in cold environment.3.In the future studies, the influence of material deterioration due tolong-term freezing-thawing cycles on fatigue durability will beevaluated.
