![]() Some of the specimens were stored in water for times of up to one year, during which they were periodically removed from the bath to be measured for expansion and also scanned by X-ray tomography. Laboratory specimens of concrete were cast with variations in one of three possible variables of interest: air void target, potassium level or type of fine aggregate. This study describes an experimental method to quantify the internal air voids percent, air void distribution, cracks initiation and growth in concrete. The durability of concrete is influenced by factors such as air void percentage, air void distribution, and cracking.
