Liu, Baoju (author), Ye, Huiwen (author), Jiang, Junyi (author), Shi, Jinyan (author), Yalçınkaya, Çağlar (author), Šavija, B. (author)Crystalline admixture (CA) is an effective self-healing agent for mortar. However, the effects of crack parameters (i.e. crack width and cracking age) and the service environment on the self-healing behavior of CA-containing mortar are not well understood. Herein, the self-healing behavior of mortar containing a self-developed CA was assessed...journal article 2024

Wan, Z. (author), Zhang, Y. (author), Xu, Y. (author), Šavija, B. (author)Additively manufactured vascular networks have great potential for use in autonomous self-healing of cementitious composites as they potentially allow multiple healing events to take place. However, the existence of a vascular tube wall may impede with the healing efficiency if it does not rupture timely to release the healing agent. The...journal article 2023

Hernandez Santana, M. (author), Grande, A.M. (author), van der Zwaag, S. (author), Garcia, Santiago J. (author)Broadband dielectric spectroscopy (BDS) is introduced as a new and powerful technique to monitor network and macroscale damage healing in an elastomer. For the proof of concept, a partially cured sulfur-cured natural rubber (NR) containing reversible disulfides as the healing moiety was employed.

Mousavi Rad, Sina (author), Kamboozia, Neda (author), Anupam, K. (author), Saed, Seyed Ataollah (author)First, porous asphalt (PA) pavement possesses a lower strength and lifetime compared to typical dense-grade asphalt mixtures due to its large empty space structure. Second, PA pavements' fatigue life and durability are affected significantly by climate factors; the two most critical factors being aging conditions and moisture actions. Third,...journal article 2022

Susa, A. (author), Bose, R.K. (author), Grande, A.M. (author), van der Zwaag, S. (author), Garcia, Santiago J. (author)Traditional polyetherimides (PEIs) are commonly synthesized from an aromatic diamine and an aromatic dianhydride (e.g., 3,4′-oxidianiline (ODA) and 4,4′-oxidiphtalic anhydride (ODPA)) leading to the imide linkage and outstanding chemical, thermal and mechanical properties yet lacking any self-healing functionality. In this work, we have replaced...journal article 2016

(author)Polymeric capsules can have an advantage over glass capsules used up to now as proof-of-concept carriers in self-healing concrete. They allow easier processing and afford the possibility to fine tune their mechanical properties. Out of the multiple requirements for capsules used in this context, the capability of rupturing when crossed by a...journal article 2017
