【摘要】 针对再生骨料透水混凝土表面易出现骨料剥离的病害现象，自制拉拔装置来测试再生骨料与水泥浆体的界面黏结强度，并以此作为再生骨料透水混凝土表面骨料抗剥离能力的表征指标之一。系统研究了水胶比(质量比)为0.25,0.30,0.35,0.40,骨料粒径4.75 mm～9.5 mm和9.5 mm～16 mm两种因素对界面黏结强度的影响。试验结果表明：水胶比和骨料粒径对界面黏结强度均有较大的影响；当水胶比相同时，骨料粒径较大则界面黏结强度较大；当骨料粒径相同时，水胶比过大或过小都会降低界面黏结强度。更多还原

【Abstract】 Due to the likelihood of aggregates peeling off from surface of recycled aggregate permeable concrete, a self-made tension device is used to test tensile properties of interface particle bonding, which is used as one characterization indicator for peeling-resistance capability of aggregates on interface of recycled aggregate permeable concrete. Systematical study of two factors, including water-binder ratios, ranging from 0.25, 0.30, 0.35 to 0.40, and aggregate sizes, ranging from 4.75 mm～9.5 mm to 9.5 mm～16 mm, was implemented on bonding strength of the interface. Test results show that water-binder ratio and aggregate particle size have a significant impact on bonding strength. Keeping water-binder ratios constant, the larger the aggregate particle size is, the greater the interface bonding strength. Keeping aggregate particle sizes constant, the most suitable water-binder ratio lies in between the series for best interface bonding strength.更多还原
