Kamat, Ameya (author), Lubelli, B. (author), Schlangen, E. (author)Crystallisation due to commonly occurring salts like sodium chloride (NaCl) is a known cause of damage in the built environment. Use of crystallisation inhibitors is a potential solution to reduce salt decay in building materials. Researchers have reported lower damage when sodium ferrocyanide (NaFeCN), a known NaCl crystallisation inhibitor, is...abstract 2023

Romero Rodriguez, C. (author), Deprez, Maxim (author), França de Mendonça Filho, F. (author), van Offenwert, Stefanie (author), Cnudde, Veerle (author), Schlangen, E. (author), Šavija, B. (author)Superabsorbent Polymers (SAP) have been recently subject of investigation as smart admixtures for cement-based materials. The properties of these polymers enable their use for internal curing, increasing freeze/thaw resistance, boosting autogenous self-healing and providing a crack self-sealing effect in cementitious composites. Except for...book chapter 2020

(author), Bos, Freek (author)Previous research has shown that the material properties of a three-dimensional printed strain hardening cementitious composite (3DP-SHCC) can significantly vary, depending on the printing system with which it is produced. However, limited research has been performed on the reproducibility of hardened mechanical properties under identical...book chapter 2022

Tabakovic, A. (author), Schlangen, E. (author)This paper presents a unique self-healing system for asphalt pavement which employs compartmented calcium-alginate fibres encapsulating an asphalt binder healing agent (rejuvenator). This system presents a novel method of incorporating rejuvenators into asphalt pavement mixtures. The compartmented fibres are used to distribute the rejuvenator...book chapter 2020

Chang, Z. (author), Schlangen, E. (author), Šavija, B. (author)This paper reports an extended lattice model for printing process simulation of 3D printed cementitious materials. In this model, several influencing factors such as material and geometric nonlinearity are considered. Using this model, green strength of cementitious material is investigated, deformation and crack pattern can be derived, which...book chapter 2020

Xu, Y. (author), Schlangen, E. (author), Šavija, B. (author)Mechanical behavior of cementitious cellular composites (CCC) with auxetic behavior was investigated under uniaxial compression and cyclic loading. Three cellular structures with different geometrical parameters are designed and prepared by 3D printing technique. Meanwhile, plain mortar and fiber reinforced mortar are used as constituent...book chapter 2020

Matos, Ana Mafalda (author), Nunes, Sandra (author), Chaves Figueiredo, S. (author), Schlangen, E. (author), Aguiar, José L.Barroso (author)The subject of this paper is the extent to which, during wetting–drying cycles, chloride ions can penetrate Ultra-high-Performance Fibre Reinforced Cementitious Composites (UHPFRC) specimens subjected to combined mechanical and environmental load. Pre-cracking was obtained by subjecting prismatic specimens (40 × 40 × 60mm<sup>3</sup>) to four...book chapter 2021

Kamat, Ameya (author), Lubelli, B. (author), Schlangen, E. (author)Sodium chloride (NaCl) is one of the most commonly occurring weathering agents, responsible for a progressive damage in mortar. Current solutions to mitigate salt damage in mortar, such as the use of mixed-in water repellent additives, have often exhibited low compatibility with the existing building fabric. In the last years, research has...book chapter 2023

Liang, M. (author), Schlangen, E. (author), Šavija, B. (author)Stress evolution of restrained concrete is directly related to early-age cracking (EAC) potential of concrete, which is a tricky problem that often happens in engineering practice. Due to the global objective of carbon reduction, Ground granulated blast furnace slag (GGBFS) concrete has become a more promising binder comparing with Ordinary...book chapter 2023

Pan, Z. (author), Schlangen, E. (author)In self-healing concrete, healing agents (including the bacteria and nutrients for the bacteria) are often sealed in capsules to survive the mixing of concrete. When the crack occurs, these capsules can be damaged, the healing agents can be released and the chemical actions can be activated. This research mainly focuses on the probability...conference paper 2015
