Quality control of fresh concrete by advanced dispersion and attenuation characteristics of stress waves Ghent University
This project seeks a methodology based on stress wave techniques that can assess crucial parameters of the concrete performance from the moment after mixing, when there is still the possibility to adjust or reject the material before being permanent part of the structure. The investigation will be based on elastic waves (using innovative dispersion and attenuation parameters) and acoustic emission (AE).
The Mechanisms Governing the Robustness of Fresh Self-Compacting Concrete KU Leuven
This thesis deals with the robustness of fresh self-compacting concrete (SCC). As no external compaction is necessary, many problems caused by a poor compaction are evaded and a denser reinforcement or more complex formworks can be applied when using SCC. Although reduced construction times, less labour costs, and an improved pumpability encourage the usage of SCC, an inferior robustness – the capacity to tolerate small variations in the mix ...
Mix Development and Performance of Concrete with Treated Slag from Copper Production as Cement and Sand Replacement KU Leuven
By incorporation of MFS-slag (modified iron-silicate slag) in concrete mixtures at high cement and/or aggregate replacement levels, the DUSC project strives for (i) maximum residue valorisation and avoidance of waste disposal, and (ii) more durable and sustainable reinforced concrete structures, with a low carbon footprint, high service life and good recyclability. MFS-slag based concrete (‘MFS-concrete’) is targeted which can be used as ...
Creep of synthetic fibre reinforced concrete. KU Leuven
As the most widely used construction material, concrete is constantly in development with continuous advances made in the fields of material science, concrete technology and reinforcement systems. The development of fiber reinforced concrete (FRC) has significantly impacted all three fields. Since the first trials with FRC in the 1960s, the material has undergone significant improvements in both the quality of the materials as well as the ...

Active control of concrete curing by acoustic emission (ACCCAE) Ghent University
Acoustic monitoring has recently significantly contributed to the understanding of processes in fresh cementitious media. The ambition of this project is, for the first time, to use the real time acoustic emission (AE) behavior to control the curing of the material, aiming at better mechanical properties and at the same time use the recorded data to make projections towards the final quality of the hardened medium. Processes like hydration ...
Development of viable 3D-printing methods for digital fabrication of reinforced concrete KU Leuven
In recent decades, 3D printing technologies have been increasingly used in construction. This is mainly the printing of individual objects made of concrete and steel (buildings, bridges). Owing to the fact that reinforced concrete is the main building composite material in the world, several additive manufacturing technologies have been developed using various techniques for combining freshly extruded concrete with reinforcement. However, the ...
