| 摘 要： | 为研究机制生土砖与砂浆法向粘结性能的影响因素，分别对凿毛和未凿毛的机制生土砖与改性砂浆在7、14、28 d龄期下共72个试件进行拉伸粘结强度试验，探讨不同界面状态的机制生土砖在不同龄期下与改性砂浆法向粘结强度的变化规律和破坏形态特点，分析界面状态、龄期等因素对机制生土砖与砂浆法向粘结性能和破坏形态的影响。研究表明：机制生土砖与砂浆间的法向粘结强度值与界面状态和龄期有关，法向粘结强度随龄期的增大而提高，界面状态为凿毛时法向粘结强度有所降低，砂浆种类对机制生土砖与砂浆法向粘结强度影响显著。

| Abstract: | In order to investigate the influence factors of normal bonding properties between mortar and mechanical pressing raw-soil brick, the tensile bond strength test was made between mortar and mechanical pressing raw-soil brick with different interfacial condition.There were 72 specimens in total and three ages including 7d, 14d and 28d.The failure mode and the change rules of normal adhesive strength in different ages between raw-soil brick and mortar were explored. The influence of interfacial condition and ages on normal adhesive strength and failure mode was studied. The results show that interfacial condition and ages both have an influence on normal adhesive strength, which is improved along with ages and is decreased because of roughing. The normal bonding properties between mortar and mechanical pressing raw-soil brick is impacted by the type of mortar evidently. The reference for engineering application of raw soil mechanism brick is provided by the research results. |
