Webrelaxation. Thermal or hygral shrinkage histories can be prescribed, or analysed by the FE solution of non-linear diffusion equations governing moisture migration and heat conduction. The model has been shown to simulate concrete and masonry behaviour with reasonable accuracy by the verification and validation analyses of experiments. WebN is the hygral shrinkage coefficient of the system (non-linear with relative humidity), V f is the volume fraction of aggregate in the system (unitless) , RH is the ambient relative humidity of the environment (unitless), and n is a value between 1.2 and 1.7 (normal aggregate) and cement paste.
