Effect of fly ash and metakaolin on early-age autogenous shrinkage and mechanical properties of ultra-high-performance concrete

To address the severe autogenous shrinkage and high cracking risk caused by the extremely low water-to-binder ratio in traditional ultra-high-performance concrete (UHPC), this study incorporates fly ash (FA, 10%, 20%, and 30%) and metakaolin (MK, 5%, 10%, and 15%) individually, as well as in binary...
