Comprehensively considering the positive contribution of energy conservation and the reduction of the construction skill requirement for workers, a new type of interlocking hollow block using recycled aggregates concrete (IHAC) with the compressive strength defined as MU10 was proposed, which could help improve more than 56% of the construction efficiency compared to common used concrete hollow blocks. In order to study the shear properties and promote its application in building engineering, the shear strength of 10 groups (three specimens for each group) of masonries considering different axial stress level and whether or not to use concrete in the grouting holes were studied, and the failure mode as well as the shear strength of the masonries were analyzed. And then, the calculation formulas for predicting the shear strength of the IHAC masonry were obtained by using the parameter fitting method based on the Coulomb failure theory, which could well reflect the parabolic shaped changing characteristic of the shear strength with the increasing of the axial stress, and the maximum difference was within 18% between the calculated and test results.

综合考虑节能的积极作用和降低工人的施工技能要求，提出了一种新型的以再生骨料混凝土（IHAC）制成的联锁空心砌块，其抗压强度定义为MU10，可以帮助提高56以上的强度与常用的混凝土空心砌块相比，建筑效率提高了5％。为了研究剪切特性并促进其在建筑工程中的应用，研究了10组（每组三个样本）砌体的剪切强度，这些砌体考虑了不同的轴向应力水平以及是否在灌浆孔中使用混凝土，并且分析了破坏模式以及砌体的抗剪强度。然后，
