S.E. Pihlajavaara,H. Paroll +1 more
TLDR
In this article, the correlation between the permeability and the strength of concrete was studied by means of new methods of measuring the air and water in concrete. But the scatter of the results is rather large, probably due to the heterogeneous character of concrete containing aggregate particles which are large in comparison with the test cavity.About:

16 – Permeation Analysis
TL;DR: In this article, the authors describe the process of transport of fluid flux in terms of adsorption, diffusion, absorption, and permeability in concrete, and the volume and size of the capillary voids depend on the distance among unhydrated cement particles in the freshly mixed cement paste and the degree of hydration.

Methods of measuring the air and water permeability of concrete
TL;DR: In this article, the authors describe simple and portable apparatus for estimating the air and water permeability of concrete in situ. The methods used require a small hole 5·5 mm diameter and 30 mm deep to be drilled in the specimen The hole is plugged with a catalysed liquid silicone rubber which sets to give a resilient seal to the small cavity in the concrete.
