Influence of high curing pressure on the mechanical performance and micro-scale characterization of concrete

Key Points

• To explore the effect of high curing pressure on the mechanical performance and microstructural evolution of concrete.
• Utilized macro and micro experimental techniques to assess concrete properties under high curing pressures.
• Examined compressive strength, elastic modulus, and microstructural changes, including void distribution and hydration products.
• Analyzed the evolution of void structure and hydration degree in concrete samples.
• Initial loading phase of samples under pressure significantly shortened.
• Compressive strength and elastic modulus increased, indicating improved mechanical performance.
• Void structure of concrete became refined, showing a trend from larger to smaller pore sizes.
