混凝土氯离子渗透试验研究

Experimental Study on Chloride Ion Penetration Performance of Concrete

钢筋混凝土结构耐久性是目前土木工程界需要重点解决的问题之一。通过对混凝土抗氯离子渗透性指标之间的对比试验研究,提出了初始电流计算电通量的方法,并论证了该方法在施工中应用的可行性;并进一步对渗透系数和电通量试验时的初始电流相关性进行分析,提出对电通量和渗透性试验的综合法,可以使指标一致,有利于实际应用和对比。

Durability of reinforced concrete structures is now one of the questions that needs be solved in the civil engineering sector. Through the comparison research on the indexes of anti-chloride permeability of concrete, the method using initial current to calculate electric flux is proposed and the feasibility of this method in construction is proved; the correlation of the initial currents of the tests of electric flux and penetration is further analyzed, then a synthetic method to test the electric flux and permeability coefficient is proposed, which can make the indicators consistent and be beneficial to practical application and comparison.
