活性粉末混凝土疲劳后剩余抗压强度试验研究
Experimental study on residual compressive strength of RPC under fatigue loading
摘要
Abstract
In order to investigate the evolution law of residual compressive strength for reactive powder concrete ( RPC) under fatigue loading, the fatigue tests were carried out.24 cylinders were cast for testing and divided into 3 groups.By measuring the compressive strength of some RPC specimens, the relationship between initial compressive strength and resonance frequency was established firstly.On that basis, the constant amplitude and two-stage amplitude fatigue tests were carried and the residual compressive strength of RPC specimens were measured after fatigue.Experimental results show that the attenuation of post-fatigue residual compressive strength of RPC decreased with increase of recycle ratio.On the other hand, the attenuation rate increased with increase of recycle ratio.An fitting formula about the attenuation of post-fatigue residual compressive strength and recycle ratio was deduced.The calculated values which come from fitting formula are in good agreement with measured values.关键词
