Length changes of autoclaved aerated concrete exposed to cyclic wetting and drying
Original language description
The linear hygric expansion coefficient, alpha(w), of three commonly used autoclaved aerated concretes (AAC) is determined as a function of moisture content by volume, w, in the range from capillary water saturation to dry state in two consecutive wetting-drying cycles. A hyperbolic function alpha(w)(w) = A/w(2) is proposed as the most suitable mathematical representation of the experimental data, for an application in the hygro-mechanical computer simulation tools. A basic assessment of the supposed hygro-mechanical performance of the investigated AAC in common building structures shows that the current standards do not provide much help to the designers because they treat the moisture-induced length changes of AAC in a rather simplistic way. Therefore, a characteristic hygric strain defined by the length change between two typical hygric equilibrium states is proposed instead, for obtaining a basic estimate of the maximum tensile stress. In the case such estimate leads to unfavorable
