| 摘 要： | 当混凝土的也隙液相碱度降低到１１．５以下时，钢筋纯化膜遭到破坏。试验表明，与普通混凝土相比，高掺量粉煤灰混凝土长龄期孔隙液相碱度出现了明显的降低，其护筋性更应该重视长龄期孔隙液相碱度。

| 关 键 词： | 碱度 护筋性 高掺量粉煤灰混凝土 孔隙液 |

| Abstract: | Deactivated film of reinforcing bar is destroyed when degree of alkalinity in pore fluid of concrete is lowed 11.5. Experimental results showed that degree of alkalinity in pore fluid of high-volume fly ash concrete is reduced obviously and long age degree of alkalinity in pore fluid should be taken seriously in corrosion resistance of high-volume fly ash concrete. |

| Keywords: | degree of alkalinity corrosion resistance high-volume fly ash concrete |
