Introduction
The water absorption coefficient w is used for measuring at which rate a building material absorbs water:
Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle w= \frac {W[kg/m^2]}{\sqrt{t}[h^{0.5}]}}
W = amount of water [kg/m²], t = time in [h]
The water absorption coefficient indicates, how many kg of water per hour one square meter of material absorbs through capillary action.
| The water absorption coefficient is used to measure the rate of moisture absorption of building materials. |
Most common is the following classification of the water absorption coefficient (in kg/(m2*h0.5))[1][2]:
