高温中植筋胶拉伸抗剪强度试验研究
摘要
为了研究高温中植筋胶的拉伸抗剪强度
进行了57个植筋试件在不同温度下的拉拔试验。试验温度共11个
温度范围为25~350℃。采用电炉加热升温
当到达设定温度后立即进行拉拔实验
每个温度下做5组试件。试验中量测电炉温度
植筋试件温度
植筋滑移和拉拔力。试验结果表明:随着温度升高
植筋胶的拉伸抗剪强度显著下降
当温度高于350℃后
植筋胶基本丧失承载力
约为常温下的4%左右。
Abstract
To study the shear strength of anchorage adhesive under high temperature
57 specimens were tested.The test temperature ranges from 25℃to 350℃.The specimens were heated by the electric furnace. When heated to the fixed temperature
the specimen was tested.Five specimens were tested in each temperature.In the test
records were made on the furnace temperature
specimen temperature
slip and the force.The test results show that the shear strength decreases with temperature increasing
and the shear strength is about 4%of that in the ambient temperature when the temperature is above 350℃.
