This paper discusses the effect of the aggregate grading and water/cement ratio on the air permeability coeffi-cient. An aggregate grading with more sand than coarse aggregates has resulted more beneficial from the point of view of concrete air permeability. This fact can be attributed to a denser skeleton formed by the finer aggre-gates.
