This paper presents the development and evaluation of a practical, adequate, and appropriate means of estimating the intrinsic permeability of concrete. The study is based on the author's own experimental results and observations reported in literature. A correlation model between effective and intrinsic permeability is developed, and a means of estimating intrinsic permeability for planned concrete elements from material and mix properties is investigated. The multiplicative effect of compressive strength and coarse aggregate content is shown. Although various multiple linear regression models are considered, it is shown that practical simple linear regression models can be considered for the estimation of intrinsic permeability of existing or planned concrete elements.

本文介绍了评估混凝土固有渗透性的实用、充分和适当方法的开发和评估。该研究基于作者自己的实验结果和文献报道的观察结果。开发了有效渗透率和固有渗透率之间的相关模型，并研究了一种从材料和混合特性估计计划混凝土元素的固有渗透率的方法。显示了抗压强度和粗骨料含量的乘法效应。尽管考虑了各种多元线性回归模型，但表明可以考虑实用的简单线性回归模型来估计现有或计划的混凝土构件的固有渗透性。
