【摘要】：砌筑膠凝材料的耐久性對于砌體結(jié)構(gòu)的穩(wěn)定性有重要作用。對取自兩處典型巖土質(zhì)砌筑文物建筑海龍屯飛龍關(guān)、飛鳳關(guān)遺址和馬爾康直波雕群的膠凝材料樣品性能進(jìn)行了測定,表明原砌筑膠凝材料基本為就地取材,采用傳統(tǒng)工藝及傳統(tǒng)方法制作而成。由于未經(jīng)改性,傳統(tǒng)膠凝材料在成分及結(jié)構(gòu)方面的缺陷,也成為后期劣化的源頭。微結(jié)構(gòu)是影響膠凝材料結(jié)構(gòu)強(qiáng)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.
