水硬性石灰因其可持续性与材料相容性优势，近年来在建筑与文物保护领域受到关注，然而，因早期强度增长缓慢，限制了其在快速加固场景中的应用。以钾长石与石灰石共同煅烧制备的合成水硬性石灰K3为对象，在标准养护与加速碳化养护条件下，对比分析砂浆试件的收缩率、孔隙率、力学性能、弹性波速以及物相与微观结构演变规律。结果表明，加速碳化可显著改变K3的反应进程，28 d时试件孔隙率较标准养护降低约9.7%,抗折和抗压强度分别提高至3.20 MPa和12.54 MPa,弹性波速整体升高，反映出内部结构连续性与强度的增加。TG-DSC与SEM显示，碳化环境促进了Ca(OH)2的快速消耗和大量CaCO3的沉积，形成由CaCO3与C-S-H协同构建的致密复合骨架结构。研究表明，通过合理调控养护环境即可推动合成水硬性石灰实现早期强度与结构稳定性的显著提升，为石质文物和历史建筑遗存的快速加固与修复提供了可行路径。
Abstract：Hydraulic lime has attracted growing interest in building and cultural heritage conservation because of its sustainability and good compatibility with original substrates. Its slow early strength development, however, restricts its use in situations where rapid consolidation is required. In this study, a synthetic hydraulic lime(K3) obtained by co-calcination of potassium feldspar and limestone was subjected to standard curing and accelerated carbonation curing, and the drying shrinkage, porosity, mechanical properties, ultrasonic pulse velocity, as well as phase assemblage and microstructural evolution of mortar specimens were compared. The results show that accelerated carbonation markedly alters the reaction process of K3: At the 28th day, porosity is reduced by about 9.7% relative to standard curing, while flexural and compressive strengths increase to 3.20 MPa and 12.54 MPa, respectively. The overall increase in ultrasonic pulse velocity indicates improved internal structural continuity and stiffness. TG-DSC and SEM observations further show that the carbonation environment promotes rapid consumption of Ca(OH)2 and substantial precipitation of CaCO3, leading to a dense composite skeleton formed jointly by CaCO3 and C-S-H. Taken together, the results suggest that appropriate control of the CO2 curing environment can significantly enhance the early strength and structural stability of synthetic hydraulic lime, providing a practical option for the rapid consolidation and repair of stone relics and historic masonry structures.
