Effect of axial compressive damage on gas permeability of ordinary and high-performance concrete [PDF]

Cement and Concrete Research, 2001
Gas permeability is commonly used to evaluate durability characteristics of concrete. However, these values are often achieved using never stressed or damaged specimens. The objective of this study is to examine experimentally the effect of axial compressive loading on the pemeability of three different types of concrete: ordinary concrete (OC), high ...
