Abstract
The freeze-thaw damage pattern of concrete is linked to the water contained in the pore system, which is referred to as the saturation level. If a certain critical saturation level is exceeded, micro-cracking will occur even within a single or very few freeze-thaw cycles and lead to progressive destruction of the concrete matrix. It is crucial to quantify the influence of freeze-thaw cycling on the saturation level of the pore system in the concrete to develop a forecast model to predict freeze-thaw resistance. Non-destructive nuclear magnetic resonance imaging shows that the water absorption of concrete is significantly accelerated under freeze-thaw cycling, as compared with water absorption at a constant temperature level.
