摘要
本文介绍了用混凝土电导、或通过混凝土的电荷量,来快速测定混凝土抵抗氯离子渗透性能的试验方法。研究表明,电导和电荷量,均能较好地反映出透过具有不同技术条件的混凝土的氯离子量。并为检验和控制海工混凝土质量,提供一种有效的测试手段。
This paper presents a test method of measuring the amount of charge passing through concrete in direct current electric field,which can be used to rapidly assess the permeability of concrete to chloride ions.And the possibility to evaluate permeability of concrete to chloride ions by means of measuring the conductance of concrete also is studied. It is showed from the result that there is a good correlation be- tween charge or conductance of various types of concrete and the amount of chloride ions penetrating through them.This test method can be used as an effective means for examining and monitoring the quality of concrete in the ocean engineering structure.
