【摘要】 对钢筋在陶粒混凝土中的锈蚀及其机理进行了电化学研究.结果表明,钢筋在陶粒混凝土中的锈蚀速率小于相同条件下的普通混凝土,而形成这种结果的原因一方面是由于在陶粒混凝土中钢筋的钝化膜电容较大,另一方面则是由于陶粒与水泥浆体之间的相界面抑制了氯离子的扩散.更多还原

【Abstract】 The corrosion of rebar in pottery grain concrete was studied by electrochemical methods. It is shown that the corrosion rate of rebar in pottery grain concrete is lower than that in ordinary concrete under the same conditions. It is because the capacitance of passivation film is larger in pottery grain concrete as compared with that in ordinary concrete and the chloride diffusivity is smaller in the former case than that in the latter case.更多还原
