抗压和抗拉强度是砂浆的主要技术指标,是确定砂浆标号的依据,也是进行建筑结构设计最基本的参数。它对砌体的力学性能,特别是砌体的抗剪强度,起着极其重要的作用。为寻求提高砌体的抗压、抗剪、抗拉强度和建筑物抗震性能的途径。我们在开展“空心砖砌体抗震性能试验研究”的同时,进行了107胶砂浆及其砌体抗剪强度试验,取得了一些令人满意的技术效果。
Compression and tensile strength are the main technical indicators of mortar, the basis for determining the mortar number, and also the most basic parameters for building structural design. It plays an extremely important role in the mechanical properties of masonry, especially the shear strength of masonry. To seek ways to improve the masonry’s resistance to compression, shear, tensile strength and earthquake resistance of buildings. While carrying out the “Research on Seismic Performance of Hollow Brick Masonry”, we conducted the shear strength test of 107 mortar and its masonry and achieved some satisfactory technical results.
