This study explores the impact of an expansive agent (EA) on the performance of internally cured ultra-high-performance concrete (UHPC) using pre-wetted biochar to achieve a synergistic effect in mitigating autogenous shrinkage. Here, the biochar provides internal curing water to mitigate self-desic...
