Ultrasonic evaluation of self-healing cementitious materials with superabsorbent polymers: Mortar vs. concrete
Abstract
The inclusion of superabsorbent polymers (SAPs) has become increasingly attractive to promote the self-healing<br/>ability of cementitious materials, thereby reducing the costs related to manual repairs. To advocate the use of<br/>these additives within large-scale constructions, an assessment of the self-healing ability is needed to ensure the<br/>safety of infrastructures. A non-destructive evaluation method was found in the adoption of ultrasonic moni-<br/>toring. Thanks to the sensitivity of ultrasound to the elastic properties, the technique allows to determine the self-<br/>healing effectiveness and to compare the healing capacity between different mixtures. However, most studies<br/>concerning ultrasonic assessments of the healing evolution were conducted on mortars, lacking large aggregates.<br/>Therefore, to upgrade to the most commonly used construction material, self-healing of concrete is monitored,<br/>and its performance is compared to mortar. Ultrasonic surface wave monitoring shows the potential to evaluate<br/>the crack closure in either mixture and the effect of different SAPs included.
