Effect of Dry-Wet Circulation on Moisture Absorption of Autoclaved Aerated Concrete

Table 2

Model fitting of moisture adsorption kinetics curve.

Model	Model expression
Double exponential model	y = y0 + Ae^−Cx + Be^−Dx
Weibull model	y = A − (A − B)e^−(kx)D
Zero-order process	y = A + Bx
First-order process	y = A(1 − e^−Bx)

Note: y = equilibrium moisture absorption rate; x = time; y₀, A, B, C, D, and K = corresponding model constants.
