高温下化学植筋的粘结性能

摘要

Pull out tests were carried our for untreated and thermally treated planting bars in C15 concrete when using inorganic chemical painting glue. Experimental results show that the bonding strength of thermally treated planting bars is higher than that of the untreated, and the influence of the strength of concrete on the bonding strenght is almost not controlled by temperature.%在无机化学植筋胶植筋状态下,对C15混凝土基材上的常温、高温加热过的植筋进行拉拔试验,得出高温加热过的植筋粘结强度大于常温状态下的植筋粘结强度；对C15、C30混凝土基材上的高温加热后的植筋进行拉拔试验,得出混凝土强度对植筋粘结强度的影响几乎不受温度的控制.
