| 摘 要： | 通过试验研究，探讨了不同强度等级的矿渣混凝土和普通混凝土在７ ｄ，２８ ｄ，９０ ｄ，１８０ｄ，３６５ ｄ 龄期的抗压强度，研究了矿渣混凝土的抗冻融耐久性．试验表明，强度等级、养护条件、矿渣掺量等因素对矿渣混凝土的强度、抗冻融耐久性有着显著的影响；矿渣混凝土的抗冻融耐久性明显优于同等级的普通混凝土；矿渣掺量愈大，矿渣混凝土的抗冻融耐久性愈差

| Abstract: | The freeze thaw durability and strength properties of OPC and GGBS concrete at the age of 7 day,28 day, 90 day,180 day and 365 day were investigated.Test results show that the freeze thaw durability and strength of GGBS concrete are greatly affected by the strength grade,curing regime and GGBS replacement level.The freeze thaw durability of GGBS concrete is much better than the same strength OPC concrete.The higher the GGBS replacement level,the lower the durability factor of the GGBS concrete. |
