Abstract

This paper introduced a kind of high-performance concrete employed for bridge expansion joints and characterized by key components of multiple microfibers and polymers. Experimental studies show that compared with ordinary concrete, steel fiber-reinforced concrete, and polypropylene fiber-reinforced concrete commonly adopted in bridge expansion joints, the shock resistance performance of high-performance concrete for bridge expansion joints has significantly improved, which holds certain application significance for solving or delaying early damage of expansion joint concrete and reducing maintenance costs.
