Angst, Ueli M. (author), Rossi, Emanuele (author), Boschmann Käthler, Carolina (author), Mannes, David (author), Trtik, Pavel (author), Elsener, Bernhard (author), Zhou, Z. (author), Strobl, Markus (author)The steel–concrete interface (SCI) is known to play a major role in corrosion of steel in concrete, but a fundamental understanding is still lacking. One reason is that concrete’s opacity complicates the study of internal processes. Here, we report on the application of bimodal X-ray and neutron microtomography as in-situ imaging techniques...journal article 2024

Verhoeven, Cas (author)The urban heat island effect is a well-known and pressing problem in cities today related to urbanisation. It is the phenomenon of an increased ambient air temperature in cities compared to the surrounding rural areas. The use of nature-based solutions has been proposed as a way to help solve this problem. These interventions use nature and...master thesis 2023

Boon, Ricardo (author)Carbon dioxide can be used during concrete production, which leads to stronger concrete as well as a sequestration method for CO2. While these technologies are developed quite far, they are currently not being used within society nor is there any systemic overview of the system and a reason why these technologies are not used. This thesis...master thesis 2023

Saravanakumar, Karthikeyan (author)The chemistry of ground granulated blast furnace slag (GGBFS) is one of the main factors affecting its reactivity. Knowing the composition of GGBFS used in aged concrete may help understand its past performance and estimate remaining service life. It is well known that GGBFS generally react slower than cement clinker. This thesis proposes that...master thesis 2023

Ruijgrok, Joris (author)Concrete half-joints are a specific support detail in reinforced concrete structures, which reduce the construction height of the total structure. The use of concrete half-joints became popular around 1950s, but decreased its interest as a result of new insights on structural behaviour and collapses of these structures. Typical issues regarding...master thesis 2023

Cheng, H. (author), Weemstra, C. (author), Hendriks, M.A.N. (author), Yang, Y. (author)Coda wave interferometry (CWI) holds promise as a technique for concrete stress monitoring. This is because the coda, which consists of multiply scattered arrivals, is the result of propagation through the medium over large distances. As such, it is sensitive to both minute structural changes and small velocity changes in that medium....journal article 2023

Wan, Z. (author), Chang, Z. (author), Xu, Y. (author), Šavija, B. (author)In this paper, optimization of vascular structure of self-healing concrete is performed with deep neural network (DNN). An input representation method is proposed to effectively represent the concrete beams with 6 round pores in the middle span as well as benefit the optimization process. To investigate the feasibility of using DNN for...journal article 2023

Awasthy, Nikhil (author), Schlangen, E. (author), Hordijk, Dick (author), Šavija, B. (author), Lukovic, M. (author)Concrete is characterized in terms of its engineering properties, mainly strength and stiffness, which are subsequently used in structural design. However, the apparent (i.e., measured) concrete properties are not intrinsic but dependent on the conditions under which the measurement is performed. Herein a combined experimental and numerical...journal article 2023
