Samenvatting

Cracking of cementitious materials poses severe problems for the mechanical performance and the durability of concrete structures. Self-healing cementitious materials provide a means of countering these issues, but the testing procedures to assess the self-healing efficiency are mostly impractical for in-situ evaluation. This study concerns the evaluation of the crack closure in cementitious mixtures with and without superabsorbent polymers by ultrasound measurements. Ultrasonic waves are sent through the cracks by means of pencil lead break tests, thereby offering information on the sound material as well as on the healing products formed within the cracks. The healing process is promoted by placing the specimens in wet-dry curing cycles and is monitored for a period of 14 days. Ultrasound was found to be sensitive to the closure of cracks, which was confirmed by the visual reduction in crack width opening, as investigated by microscopic analysis.
