Image of X-ray measurements of water movement during internal curing

X-ray images of water movement during internal curing. Red indicates drying and blue indicates wetting. Hydration time proceeds from left to right, top to bottom. Initial system consisted of a single LWA particle embedded in the center of a w/c=0.3 cement paste.
