ULTRA HIGH-PERFORMANCE CONCRETE BEHAVIORAL STUDY

Journal of critical reviews, 2022
It is investigated in the study paper how UHPC reacts when used as a bridge girder material. The early-age shrinkage, transfer length, creep behavior, and shrinkage following steam treatment of four optimized girders were all investigated. Data was gathered using vibrating wire gauges at strategic locations inside each girder after re casting.
