moisture movement

moisture movement

1. The process by which moisture moves through a porous medium, such as a wall construction, as a result of differences in vapor pressure.
2. The effects of such movement on the dimensions of a material such as concrete, mortar, cement paste, or rock.

Furthermore, thermodynamic properties aid the understanding of moisture movement that occur within the product during a post-harvest operation such as drying.
Therefore, the temperature to produce water vapour is rapidly reached, and the increasing wood permeability are the dominate factors of the controlling moisture movement (Siau 1984, Perre 2007).
Moreover, there may be resistance to moisture movement caused by surface shrinkage, which significantly reduces the drying speed (MEISAMIASL et al.

The presence of this coating and the well-known hydrophobicity of palm or groundnut oil all acted to reduce the moisture movement slightly.
Most of the previous work done on inwards vapor transport aimed at reporting the occurrence of inward moisture movement due to high temperature gradient, and a full set of data had not yet been produced and analyzed.
Think, if you will, of the vast Christmas tree plantations that have been functioning as systems that are reducing greenhouse gases, replacing the carbon with oxygen, regulating moisture movement in the atmosphere and soil, and providing habitat to animals, birds and micro organisms.
The greater the rate of energy exchange, the greater the rate of moisture movement.
Up to 95 percent of the moisture movement into house walls and ceilings is due to moisture "hitchhiking" as part of the air leaking into these spaces (as opposed to vapor diffusion through surface covering materials).
One coat will slow moisture movement, but it'll still allow the wood to dry out.
