Globally the construction is a major contributor to the severity of the anthropogenic environmental impact. The sector emits 39% of the global CO2 and is responsible of 40-50% of material flows. The focus of reducing the environmental impact in buildings is, in the past, mostly attributed to the operational energy. However, due to increasing...

For the dimensioning of concrete structures it is customary to determine the forces and stresses occurring in construction elements on the basis of the prescribed loads. In an iterative process, the final dimensions of the elements and reinforcement are then determined. This process becomes less simple if not only the external loads, but also...

Soft inclusions, such as capsules and other particulate admixtures are increasingly being used in cementitious materials for functional purposes (i.e. self-healing and self-sensing of concrete). Yet, their influence on the fracture behaviour of the material is sometimes overlooked and requires in-depth study for the optimization of mechanical...

The steel–concrete interface (SCI) is known to influence corrosion of steel in concrete. However, due to the numerous factors affecting the SCI—including steel properties, concrete properties, execution, and exposure conditions—it remains unclear which factors have the most dominant impact on the susceptibility of reinforced concrete to...

The potential of using phase change materials (PCM) in cementitious materials to mitigate damage due to thermal loadings has been recently focus of intensive research. In the case of PCM with transition temperatures near to the freezing point of water, their potential to delay frost in a cementitious matrix has been largely investigated through...

Strain hardening cementitious composites are a class of cementitious materials showing metal-like (i.e. pseudo-plastic) behavior in tension due to their multiple cracking ability. This is commonly achieved through use of fiber reinforcement (such as PVA) or, similarly, textile reinforcement (TRC). Increasing the ductility is important in...

Densification has been carried out for many years, mostly in biomass processing, animal feed production, and pharmaceutical industries. During the years, researchers and engineers attempted to improve the product quality and minimize the production costs. The most important quality parameters of solid bio-materials are the compressive...

Presented is a modified test for generating crack permeability data for cementitious materials. Single-parallel cracks were generated in mortar specimens. The width of the cracks was analysed through stereomicroscope and computer tomography, and the water permeability of the cracks was determined. Reduction factors and crack flow models were...

In this study, the use of nano-silica (nano-SiO<sub>2</sub>) and bentonite as mortar additives for combating reinforcement corrosion is reported. More specifically, these materials were used as additives in ordinary Portland cement (OPC)/fly ash blended mortars in different amounts. The effects of nano-silica and bentonite addition on...

Increasing urbanization and climate change are encouraging architects and engineers to use water as building land, adopting floating structures as a favorable solution. Floating architecture not only could help coastline cities to develop through seas and face sea level rise, but presents many other positive aspects among which particular...

Disposal of consumer waste is a major challenge in urban areas around the world. In the field of building materials, it has long been recognized that many types of wastes can be used instead of raw materials. In addition, production of binders such as Portland cement is a CO<sub>2</sub> intensive process. However, for widespread use of wastes...

Durability of buildings, the capacity to provide functional usable space for a certain time, as a concept of sustainable architecture forms the starting point and motivation for this project. As part of this main approach, the future function strategy should be introduced. This strategy contains an existing building which will be redesigned in a...

Although most people claim to prefer a more sustainable product, only a limited number of ‘green buyers’ act on their words at the moment of purchase. To find out how to get mainstream buyers to buy more sustainable products, we used data on 950 Western European buyers of 32 different vacuum cleaner models. The issue was why three out of four...

The abundance of waste plastic is a major issue for the sustainability of the environment as plastic pollutes rivers, land, and oceans. However, the versatile behavior of plastic (it is lightweight, flexible, strong, moisture-resistant, and cheap) can make it a replacement for or alternative to many existing composite materials like concrete....

Cracks in concrete structures present a threat to their durability. Therefore, numerous research studies have been devoted to reducing concrete cracking. In recent years, a new approach has been proposed for controlling temperature related cracking—utilization of phase change materials (PCMs) in concrete. Through their ability to capture heat,...

This thesis consists of a research study concerning the application and environmental performance of Fibre Reinforced Polymers (FRP) for application in movable bridge design. The research is accompanied by a proposed redesign exploiting the advantageous properties of FRP and a life cycle assessment (LCA) of multiple FRP variants’ environmental...

Abstract – The presented study focusses on the current situation of the European flat oyster (i.e., Ostrea edulis) within an ecosystem, its development and decline during past centuries and the habitat conditions nescacary to survive. Among these conditions substrate quality proofed to be an important factor for the colonization of oyster larvae...

Although the steel–concrete interface (SCI) is widely recognized to influence the durability of reinforced concrete, a systematic overview and detailed documentation of the various aspects of the SCI are lacking. In this paper, we compiled a comprehensive list of possible local characteristics at the SCI and reviewed available information...

An experimental study of the influence of autogeneous healing on chloride ingress in cracked concrete is presented. In the study, two concrete mixtures (a Portland cement mix and a blast furnace slag mix), two healing regimes (submerged and fog room regime), two cracking ages (14 and 28 days), and multiple crack widths are used as parameters. An...

For more than six decades, chromic acid anodizing (CAA) has been the central process in the surface pre-treatment of aluminium for adhesively bonded aircraft structures in Europe. Unfortunately, this electrolyte contains hexavalent chromium (Cr(VI)), a compound known for its toxicity and carcinogenic properties. The approaching ban on the use of...
