摘要
用21个试件,测定了芳纶复合材料(AFRP)与混凝土之间的抗剪粘结强度,通过改变温度,研究了温度对AFRP与混凝土间抗剪切粘结强度的影响。研究表明:在-40~60℃之间的温度段内,其抗剪切粘结强度变化较小,破坏形态均为混凝土试块的破坏;而当温度达70℃时,抗剪切粘结强度降低程度非常大,且破坏形态发展为树脂与混凝土粘结层的破坏。
Based on the 21 specimen of AFRP concrete under different temperature,an test was designed and conducted to investigate the effect of temperature on the shear bond strength. It is concluded in this paper that the effect on the shear bond strength was very small between -40℃ and 60℃, and the broken shapes were all the broken of concrete; When temperature was above 70℃, the shear bond strength was reduced quickly, and the broken shapes were changed into the broken of felt layer.
