Although there has been extensive research and several demonstration projects in Belgium and abroad, the use of recycled aggregates in concrete is still limited in practice. Several barriers were identified: lack of practical experience, limiting standards and the need for specific quality assurance. The paper describes recent developments in...

The use of recycled aggregates in new structural concrete is generally considered as a measure for lowering the environmental impact of concrete. Existing literature considers transport distances and the final performance of the concrete (linked to its composition) as main influencing factors to evaluate the environmental burdens or gains when...

According to the European Commission website, construction and demolition waste (CDW - consisting of materials such as concrete, bricks, gypsum, wood, glass, metals, asbestos, excavated soil…) accounts for approximately 25% - 30% of all waste generated in the EU. To move towards a recycling society, various policies have been launched by...

The spalling damage observed to concrete structures after severe fire exposure has been the topic of scientific research for the past decades. This phenomenon is commonly characterised by the sudden and in some cases violent breaking off of concrete pieces from the cross-section. In this thesis the derivation and the numerical results of a...

This research paper is a TU Delft Master’s thesis for graduation track in the field of Building Technology. Its main theme, digital manufacturing of reinforced concrete structures, has already been studied/researched by many other enthusiasts; but they adopted approaches mainly based on the digital production of formworks or 3D printing of...

When studying chloride-induced corrosion in reinforced concrete structures, essential information of interest is the concentration of chloride ions in the system. The absence of a reliable method for monitoring the free chloride ions justifies the attempts towards establishing a feasible practice in the application of the already known Ag/AgCl...

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...

Ageing is an inherent feature of nature and, hence, of materials, structures and systems. Yet, it seems a rather new topic in both science and engineering. The main reason for increasing attention for ageing as a topic is the growing awareness that, particularly in industrialized countries, ageing of our assets is a financial burden for the...

This paper reports on the advantages and drawbacks of available test methods for the determination of chloride content in cementitious materials in general, and the application of Ag/AgCl chloride sensors in particular. The main factors that affect the reliability of a chloride sensor are presented. The thermodynamic behaviour of silver in the...

This paper reports on the research-driven design process of an innovative thermal mass concept: Convective Concrete. The goal is to improve building energy efficiency and comfort levels by addressing some of the shortcomings of conventional building slabs with high thermal storage capacity. Such heavyweight constructions tend to have a slow...

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...

This internship was part of a programme that has been going on since 2012, and is called ‘NL-LAB’, standing for National Living Lab. This program deals with a very large database from asphalt tests and measurements, both in labs and in the field, provided by the contractors that cooperate with RWS. The questions set at the initiation of the...

The rapid economic and population growth recently drives Maputo to become more metropolitan, with construction sector as one of the pillars to support its transformation. This progressive move is, however, hindered by one of the most crucial problems: water scarcity. Water is essentially required by construction sector, especially in concrete...

The large-scale 3D printing technology created by a group of partners led by DUS Architects allows fabricating components made of thermoplastic polymers with Fused Deposition Modelling technique. These components can be used as moulds for concrete elements, providing freedom of form and unprecedented optimization opportunities. In this report...

This thesis presents a design for a topology-optimised concrete floor slab, of which the structural optimisation process is guided by manufacturability constraints from a vacuumatic formwork. The design has been obtained using an open-source, three-dimensional topology optimisation algorithm. Traditional floor systems are cost-optimised but can...

In the last few decades great progression has been made in the research and development of a fairly new type of concrete called ultra-high performance concrete (UHPC). This high-tech material has excellent material properties compared to conventional concrete and has the potential to make more slender and lighter structures. However the material...

As the bridge stock in The Netherlands and Europe is ageing, various methods to analyse existing bridges are bemg studied. Proof loading of bridges is an option to study the capacity when crucial information about the structure is lacking. This information could be related to the material (for example, the effect of alkali-silica reaction on the...
