摘　　要：对C30和C80混凝土进行了高温后及高温后高湿环境下养护一段时间后的加载试验。初步探讨了温度及水分对火灾损伤后混凝土强度的影响 。Strength recovery behaviors of fire\|damaged concrete cured in water were investigated.A total of 51 cube specimens with concrete strength grades of 30 MPa and 80 MPa were tested.From these test results,the influence of water and temperature on the fire\|damaged concrete strength is discussed.The results can provide a basis for analyzing accurately the fire\|damaged concrete members and evaluating the forced properties after their strengthening.

关 键 词：混凝土结构 抗压强度 温度 愈合 火灾 水分
