Water vapour permeability of clay bricks

Summary

The water vapour permeability of clay bricks was experimentally measured in order to draw a representative outline of industrial products without pore-forming additives. The correlations between water vapour permeability and the main compositional and microstructural parameters of both bricks and clay bodies were investigated.  A statistical model was set up in order to predict, with reasonable precision and reliability, the water vapour permeability on the basis of open porosity, bulk density, mean pore size and pore specific surface values of bricks, and the finer particle size of clay bodies.  8 refs.
