| 摘 要： | 钢筋混凝土建筑在现代建筑中最为常见,但钢筋混凝土结构建筑也有自身的缺陷,随着时间的推移,有害离子特别是Cl-的侵入,使得钢筋混凝土建筑的寿命缩短.文章研究了在模拟钢筋混凝土孔隙液中,钢筋发生腐蚀与Cl-质量分数之间的关系及pH值对腐蚀电位的影响.结果表明,随着pH值的增加,钢筋的腐蚀电位增加;钢筋被腐蚀的Cl-浓度与孔隙液的pH值有关,其中临界Cl-浓度与模拟孔隙液pH值呈半对数线性关系.

| Abstract: | The reinforced concrete is the commonest material used in the construction of buildings in modern times.But this kind of construction has some inevitable faults.With the passage of time,some disadvantageous ions and elements invade into the construction and shorten the life of these buildings.This paper studies the relationship between the steel of the reinforced concrete and critical chloride concentration in the simulative concrete crack solution.Also studied is the effect of the pH value on the open circ... |
