Abstract

To enhance the efficiency of bridge pre-cast construction, this study elucidates the benefits of steam curing by analyzing the effects of different curing regimes on the mechanical properties, durability and pore structure of concrete. The findings indicate that steam curing can markedly enhances the compressive strength and elastic modulus of concrete within the initial seven days, and maintains comparable long-term mechanical performance to that achieved through normal temperature curing. Additionally, concrete subjected to steam curing exhibits superior performance in terms of resistance to carbonation and chloride ion penetration, particularly in early ages. The resistance to carbonation and chloride ion penetration are improved significantly with prolonged constant temperature exposure and extended static resting times. Although steam curing may slightly degrade the pore structure to be slightly inferior to room temperature curing, appropriately extending the static resting times can effectively mitigate this effect. Practical applications in engineering demonstrate that selecting a steam curing regime with a constant temperature of 55℃ and an 8-hour static resting times allows the completion of prestressed tensioning 5 days ahead of schedule, thereby substantially enhancing construction efficiency.
