摘要
抗压性能是再生砂浆多孔砖砌体最主要的基本力学性能,通过标准砌体构件抗压试验,研究了再生砂浆多孔砖砌体的抗压强度、弹性模量、应力-应变规律及泊松比性能,并与GB 50003—2011《砌体结构设计规范》中的普通多孔砖砌体计算式相比较,给出了再生砂浆多孔砖砌体抗压强度设计值的建议取值。试验及结果分析表明:再生砂浆多孔砖砌体具有良好的抗压强度和变形能力。
Compression property is the main mechanical property of recycled mortar perforated brick masonry. From the compression test of masonry,it was researched the compression strength,elastic modulus,the stress-strain curve and Poisson,ratio,which were compared with the calculation formula of normal perforated brick masorry in GB50003—2011,and the recommended value of the design value of compression strength was given. The test showed that the recycled mortar perforated brick masonry had better compression strength and ability of deformation.
