为探讨适宜于岩土文物保护加固的石灰类材料，对中国古建筑中几种石灰类材料及欧洲水硬石灰的化学组成和物理力学特性进行对比研究。研究表明烧料礓石、烧阿嘎土、欧洲水硬石灰NHL5及改性捶灰的化学组成主要是气硬性胶凝材料石灰CaO（或Ca（OH）2）和水硬性胶凝材料β-硅酸钙（B—CS）及铝硅酸钙（CAS），并且这些材料的结石体具有大的孔隙率及非常小的收缩变形性等特点，适宜于岩土文物的保护加固。除此之外，石灰、糯米灰浆、蛎灰、传统捶灰的主要化学组成为石灰CaO（或Ca（OH）2），实验研究结果显示，浆液的凝固速度慢，弹性波速小且上升速率慢，结石体虽然孔隙率大，但强度在短期内较低，易产生收缩变形，不适宜用于短时间内有强度要求的岩土文物保护加固，所以有必要对蛎灰和传统捶灰做进一步的改性研究，以便更广泛地应用于岩土文物的保护加固中。

With the aim of finding suitable lime materials to enhance the geotechnical heritage sites, several kinds of lime materials used in ancient Chinese structures, as well as European hydraulic limes, were compared in terms of chemical composition and physical and mechanical properties of sintered ore and stone. It was found that chemical bumed Aga soil, water lime NHI-5 （Natural Hydralhydraulic lime-5 ） and modified on the ash is mainly composed of airsetting cementing material CaO （or Ca（ OH）2 ） and hydraulic cementitious material beta calcium silicate（ β -CS）and calcium aluminosilicate （CAS）. Therefore, the solidified forms of these materials have similar characteristics in terms of elastic wave velocity, high porosity, very little shrinkage deformation, strong frost resist- ance, water stability and other characteristics. The results suggest that they are suitable for reinforcement of relics made of rock and soil. On the other hand, lime, sticky rice mortar, oyster ash and the traditional hammer ash are composed mainly of CaO or Ca （OH）2, and their rates of solidification from a slurry is slow, the elastic wave velocity is small and the rate increases slow. Although solidified form has high porosity, its short -time strength is very low, and the body deforms easily due to shrinkage. These results suggest that slurry is not suitable for preser- vation and reinforcement of cultural relics made of rock and earth that have intensity requirements within short time- frame. Therefore, it is necessary to do further research reinforcement of cultural relics made of rock and soil. on oyster ash and classic hammer ash before using them for reinforcement of cultural relics made of rock and soil.
