本文中提出的工作的一部分，正在进行的更广泛的研究计划内的覆盖区域的结构混凝土和性能的评价，最终确定耐久性的水和离子运动。详细介绍了测试方案中采用的监测技术的发展情况，特别强调了电气方法的应用。数据突出的测试方法和结果的解释。例子给出的其他用途的数据，以提供额外的信息，混凝土的电气和物理性能，并在其水分状态。特别是，它表明，它是可能的，以确定这样的因素，如水渗透率和深度，饱和度和孔隙度的混凝土保护层，和电阻率的混凝土在钢筋的水平。
The work presented in this paper forms part of a wider research programme being undertaken on water and ionic movement within the cover region of structural concrete and the evaluation of the properties that, ultimately, determine durability. The developments in monitoring techniques employed in the testing programme are detailed, with particular emphasis on the application of electrical methods. Data are presented that highlight the testing methods and the interpretation of the results. Examples are given of other uses of the data to provide additional information on the electrical and physical properties of concrete, and on its moisture state. In particular, it is shown that it is possible to determine such factors as rates and depths of water penetration, degree of saturation and porosity of the concrete cover, and the resistivity of the concrete at the level of the reinforcement.
