沿海大气中含有一定量的氯离子,Cl^-会通过扩散、毛细吸入、渗透等形式进入混凝土的内部,影响混凝土结构的耐久性,氯离子的渗透速度除受其自身材料的影响外,环境条件因素的影响较大,通过对实际混凝土结构中氯离子沉积量梯度的检测,研究了大气氯离子对实际混凝土结构的作用和相关环境参数对氯离子作用的影响。
The coastal atmosphere includes a quantity of chloride ion.Through proliferation,capillary taking-in,penetration,and other forms, CI can penetrate into the inside of concrete structure, and affects the durability of concrete structure.Besides the influence of its ow1~ material, the factors of environmental conditions exert much influence on the penetration speed of the chloride ion.Through the gradient examination on chlo- ride ion's deposition amount in the real concrete structure ,the effect of the chloride ion on the actual concrete structure and the functional influence ofcorrelatd environmental parameter to the chloride ion was studied.
