摘要
应用交流阻抗谱中的Kramers Kronig变换对受海水长期侵蚀的混凝土和钢筋分别进行了研究 .混凝土和钢筋的稳定性可用K K变换值与实测值之间相对偏差的大小来进行衡量 .随着海水侵蚀时间的增加 ,混凝土和钢筋的稳定性越来越差 .在同样条件下 。
Reinforced concrete under the longterm intrusion of seawater has been studied by the KK transform of AC impedance spectroscopy. The stability and durability of the reinforced concrete can be measured by the relative deviation of the values measured from that calculated by KK transform. With the increase of the time of the intrusion, the concrete and the rebar is less and less stable and durable. Under the same condition, concrete with fly ash is more stable than ordinary concrete.
