- Synopsis
- The air permeability of cover concrete is considered to be important from the standpoint of the durability of concrete, and various studies have been conducted and domestic standards have been established in this regard. The authors have developed a simple air permeability test (cylinder method) that uses a cylinder, which is a highly portable measuring device that does not require a power supply, and are currently conducting investigations on this measurement method and its evaluation. This paper is a summary of the main findings regarding the usefulness of the cylinder method from studies done to date.
