Yang, Yu (author), Ji, Tao (author), Yang, Zhengxian (author), Zhang, Y. (author), Su, Wenyue (author), Wu, Ronghan (author), Wu, Zehao (author)Durability of photocatalytic coatings is a major concern in engineering practice. Here, two types of novel visible light-responsive coatings, both consisting of vinyl chloride/vinyl ester/ethylene copolymer (as a binder) and graphitic carbon nitride (g-C<sub>3</sub>N<sub>4</sub>) but different in fabrication, are proposed and applied on the...journal article 2020

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

Zhang, H. (author)Cementitious materials are heterogeneous on mutliple length scales, from nanometres to metres. Consequently, their macroscopic mechanical properties are affected by material structures at all length scales. In pursuit of fundamental understanding the relationship between their multiscale heterogeneous material structure and mechanical properties...doctoral thesis 2019

Lu, T. (author)Concrete is a brittle composite material that easily fractures under tension. Due to the fact that the early-age deformation of the concrete member is restrained by adjoining structures, cracking can occur throughout the concrete prior to application of any load. The cracks would provide preferential access for aggressive agents penetrating in...doctoral thesis 2019

Van, Rens (author)This thesis focusses on the application of vertical profiled mortar connections in precast concrete shear walls that are built up with a stacked element configuration. The goal of the project is to develop a practical modelling approach in order to be able to apply the connections in a FEM model for structural analyses. For this purpose several...master thesis 2019

(author), Papayiani, Ioanna (author)Surface repair mortars are used for the compensation, or repair, of lost portions of surface materials in historic masonry buildings. It is recommended that their design and application should be performed in a wider context of conservation values related decision making, to prioritise preservation of original fabric, authenticity of approach...journal article 2019

Granneman, S.J.C. (author), Lubelli, B. (author), van Hees, R.P.J. (author)Weathering of porous building materials caused by the crystallization of soluble salts is a ubiquitous problem in the built cultural heritage. Especially lime-based mortars are susceptible to salt decay, due to both their bimodal pore size distribution and low mechanical strength. The addition of crystallization modifiers to mortars during...journal article 2019

Kong, Sih Ying (author), Yang, Xu (author), Paul, Suvash Chandra (author), Wong, Leong Sing (author), Šavija, B. (author)This paper presents a numerical investigation of thermal response of mortar panels, incorporating macro-encapsulated paraffin in different forms. Two types of macro capsules were fabricated and tested in this study using an instrumented hot plate device. The experimental results show that macro encapsulated paraffin reduced the temperature and...journal article 2019

Apostolidis, P. (author), Liu, X. (author), Daniel, Gerald C. (author), Erkens, S. (author), Scarpas, Athanasios (author)The utilisation of synthetic fibres has been reported in the past showing enhancement of fatigue and thermal cracking resistance in asphaltic materials. However, the limited evidences about the benefits of these fibres in asphaltic materials at low material scales have been noticed. Also, the exact reinforcing mechanism of binding system in the...journal article 2019

Md Yunus, Balqis (author), Schlangen, E. (author), Jonkers, H.M. (author)This paper investigates the effects of alkaliphilic spore-forming bacteria of the genus Bacillus on the compressive strength of the mortar cube and the healing capacity of the bacteria as healing agent on mortar containing crack. The experiments were carried out using cube test, stereomicroscopy and environmental scanning electron microscopy ...journal article 2019

Kreyenschulte, Moritz (author), Schiirenkamp, David (author), Kuhling, Volker (author), Brühl, M. (author), Goseberg, Nils (author), Schiittrumpf, Holger (author)Many sea dikes along the coast of the North Sea are protected against wave loading and currents by riprap revetments that are grouted with mortar. The mortar bonds the individual stones of the top layer, thereby forming a coherent structure that is able to withstand normal forces and shear forces as well as momentums, thus leading to a planar...journal article 2019

Christian Gerald Daniel, Gerald (author)The use of synthetic fibres has been reported to enhance the performance of asphalt pavement materials in terms of permanent deformation, fatigue and thermal cracking. However, limited results about the benefits of synthetic fibres in the reinforced warm-mix asphaltic materials, and the exact mechanism of reinforcing the binding part in pavement...master thesis 2018

Dalalbashi, Ali (author), Ghiassi, B. (author), Oliveira, Daniel V. (author), Freitas, Ana (author)Textile-reinforced mortars (TRM) have recently received significant attention for the externally bonded reinforcement (EBR) of masonry and reinforced concrete structures. The fiber-to-mortar bond, the TRM-to-substrate bond, and the mechanical properties of the TRM constituents have a fundamental role in the performance of this strengthening...journal article 2018

Jing, R. (author), Liu, X. (author), Varveri, Aikaterini (author), Scarpas, Athanasios (author), Erkens, S. (author)Asphalt mortar is a mixture of bitumen, filler, and sand. Mortar plays an important role in asphalt mixtures as it serves as the adhesive between the coarser aggregates. Due to the effect of bitumen ageing, the chemical and mechanical properties of asphalt mortar evolve with time. The mortar becomes more brittle and prone to cracking, thus...journal article 2018
