摘　　要：在不同龄期条件下,通过对两组采用不同强度等级砂浆的30个混凝土小型空心砌块砌体试件进行受压力学性能试验,并对试验结果进行了比较和分析,研究了龄期对普通混凝土空心砌块砌体构件受压力学性能的影响。结合以往的研究经验及本次试验总结的规律,得出了对砌体结构房屋的施工进度及施工荷载应当加以控制的结论。通过探讨龄期对混凝土空心砌块砌体受压性能的影响,为后续课题研究提供数据资料及理论支撑。Based on experiments of the mechanics performance of 30 test units with different period conditions which were divided into two groups with different mortar strength,the experimental results were analyzed and the influence of the ages on the compressive mechanics performance of concrete hollow block masonry was studied.Combining with previous studies and the test results,suggestion was proposed that both construction schedule and working load should be controlled during the construction of masonry buildings.The purpose of studying the mechanics performance of concrete hollow block masonry was also to provide data and theoretical support to furthur research.
