【摘要】：砌筑胶凝材料的耐久性对于砌体结构的稳定性有重要作用。对取自两处典型岩土质砌筑文物建筑海龙屯飞龙关、飞凤关遗址和马尔康直波雕群的胶凝材料样品性能进行了测定,表明原砌筑胶凝材料基本为就地取材,采用传统工艺及传统方法制作而成。由于未经改性,传统胶凝材料在成分及结构方面的缺陷,也成为后期劣化的源头。微结构是影响胶凝材料结构强度的重要因素。
[Abstract]:The durability of masonry cementitious material plays an important role in the stability of masonry structure. The properties of the gelatin material samples from Feilun Guan site and Barkam direct wave carvings from two typical masonry buildings are measured. The results show that the original masonry cementitious material is based on the local material, and the traditional technology and transmission are used. Because of the unmodification, the defects in the composition and structure of the traditional cementitious material also become the source of the later deterioration, and the microstructure is an important factor affecting the structural strength of the cementitious material.
