Concrete is an important and versatile construction material used in many situations. Durability is a very important property of concrete. Durability is affected by many factors, one such factor is permeability. Even though there are methods to measure concrete permeability, there are very few well documented non-destructive methods to measure the permeability of in-situ concrete. This paper examines a new non-destructive method that measures the concrete air permeability (CAP). This method provides a fast and accurate measure of the air permeability of concrete. Concrete mixtures were cast with water to cementitious materials ratios ranging from 0.26 to 0.60 with varying amount of supplementary cementitious materials. Results show that the CAP device has the potential to be a useful tool to measure the permeability of the concrete.
