The emergence of innovative construction materials is dawning a new era of ambition within the civil engineering community. Among these innovative materials, Basalt Fibre Reinforced Polymer (BFRP) has recently surfaced with promising potential as a reinforcing material in concrete. Currently, in the Dutch concrete construction industry, the...

The use of non-destructive tests for assessing the material status of concrete structures in the Netherlands remains relatively uncommon, despite the growing demand for the preservation of existing structures under the VenR policy of Rijkswaterstaat. Skepticism towards NDTs is reflected in the scarcity of documented case studies in publicly...

Over the last 15 years or so, research has revealed the great self-healing prospects possessed by asphaltic mixtures. Researchers have proposed novel methods to harness this capability, aiming to prolong the service life of asphalt pavement, particularly in porous asphalt. To date, the most promising of the healing methods is the combined...

When concrete is subjected to imposed deformations, stresses may develop. If at any point in time this stress exceeds the tensile strength of the material, the concrete will crack. Early-age cracking of concrete structures may lead to problems with durability, serviceability and aesthetics. During hardening of concrete the material properties...

Since 2006, the Delft University of Technology has been working on the development of bacterial self-healing concrete (BSHC). The self-healing ability of this concrete is based on a biological mechanism, in which mineral producing bacteria are added to repair cracks autonomously. This not only improves the durability of concrete structures, but...

The changing climate and the need for a new purpose for End-of-Life concrete increased the importance and interest of concrete recycling. To decrease the environmental footprint of concrete, in which cement has the highest contribution, it would be of great importance to be able to recycle cement, which would positively affect the environment....

In this thesis a parametric finite element model has been developed to predict the printability of concrete structures of arbitrary geometries. The model can be used to effectively explore design and process parameters to optimize printed objects. In addition, the model can be used to improve the reliability of the printing process, reduce the...

The objective of this research project is to verify whether 3D printing of concrete (3DPC) reduces the environmental impact by increasing the structural efficiency. During the literature study, numerous articles were identified that claimed an increase of structural efficiency by using 3DPC to reduce material use. Some of these articles suggest...

Steel fibre reinforced concrete (SFRC) is nowadays used as a construction material for pavement and industrial floors in The Netherlands. The common used SFRC mixture, is concrete strength class C30/37 mixed with circa 35 kg/m3 of steel fibre. <br/>The details of the concrete composition mixed with steel fibres are ignored. The mechanical tests...

Strain hardening cementitious composite is a new generation material with increased ductility and improved cracking behaviour as compared to traditionally used Normal Strength Concrete (NSC). An important charactersitic of SHCC is the ability of the fibers (2% PVA) in the composite mixture to bridge the cracks and there by preventing...

In the year 2006, Delft University of Technology started researching ‘Strain hardening Self-healing concrete’ (SSC). The reason for this research was the desire to increase the durability of concrete. This depends mostly on the reinforcement.<br/> To ensure a certain lifespan of concrete structures, a minimum cover depth has to be applied....

CoRncrete is a corn starch based bio-material formed by mixing corn starch with water and sand, and heating the mix in a microwave or oven. This heating process results in the formation of a hardened material. A constant corn starch to sand proportion of 1:5 has been adopted in this study. The transformation of CoRncrete from a semi-solid to a...

“[Strain-hardening cementitious composites (SHCC)] are a new class of [fiber reinforced cementitious] composites characterized by a strain-hardening behavior in tension after first cracking accompanied by multiple cracking up to relatively high strain levels.” In order to contribute to the transition of common relatively thin SHCC elements for...

This thesis focuses on assessing the crack width and durability at the outside of an immersed tunnel in case of fire inside the tunnel. Previous research (for instance Nieman [20]) addressed only the heating phase of a tunnel while also the inevitable cooling phase may have a large influence on the crack width. A user supplied code was written...

In the Netherlands blast furnace slag (BFS) cement is commonly used. Concretes with this type of cement are known for good durability properties. Where concrete is designed to crack in order to let the incorporated steel reinforcement take over tensile stresses, it is mainly for durability reasons that non-designed cracking of concrete is...

The Solid House Foundation uses inflatable hemisperical formwork to build concrete dome dwellings. In this thesis a study is made of possible optimization of this building concept. Main occasion is the increasing price of rebar and the bad availability of rebar in most regions where the SHF is active. As SHF is now involved in a large housing...
