再生混凝土耐久性试验研究及服役寿命模型

摘要

Design different recycled aggregate replacement rate of recycled concrete blocks,through RCM tests on the chloride ion diffusion coef-ficient of regeneration. The function relation between the diffusion coefficient and the substitution of recycled aggregate is established,then build the service life and the aggregate of recycled aggregate concrete to replace the relation model between the rate of chloride ion erosion environment.%设计制备了不同再生骨料取代率的再生混凝土试块，通过RCM试验研究了再生混凝土氯离子扩散系数。拟合了扩散系数与再生骨料的取代之间的函数关系式，并据此建立了氯离子侵蚀环境下再生骨料混凝土的服役寿命与骨料取代率之间的关系模型。
