【摘要】 主要探讨亚硝酸盐抑制碳化引起的混凝土中钢筋腐蚀效果,通过试验发现亚硝酸盐含量越大,抑制腐蚀效果越显著,当亚硝酸钠含量达到2 5%时,能够完全抑制碳化引起的混凝土中钢筋腐蚀。更多还原

【Abstract】 In this paper,we have studied the effect of sodium nitrite which prevents steel corrosion caused by concrete carbonation.This study confirmed that higher nitrite content had obvious effect on protecting reinforcing bars from corrosion.It is 25% that can preserve the passive state of reinforcements adequately when concrete was carbonation.更多还原
