摘　　要：对再生混凝土进行了碳化、循环冻融、抗渗和复合因素下的耐久性试验研究,比较了再生混凝土和普通混凝土的碳化速度、抗冻、抗渗等耐久性能。对再生混凝土的冻融和抗渗复合耐久性能进行了初步试验研究,结果表明,再生混凝土对这种叠加损伤更为敏感,受到的破坏也更大。The experiments on carbonation resistance,freezing-thawing cycle,impermeability and durability under multi-factors conditions of recycled aggregate concrete are researched,the carbonation speed,freezing-thawing resistance and impermeability durability of the recycled aggregate concrete and the ordinary concrete are compared.The preliminary experimental research of freeze-thaw and anti-permeability composite durability of recycled aggregate concrete has carried on,the results show that the superposition damage of recycled aggregate concrete is more sensitive,and the damage is greater.
