This dissertation originates from an investigation about the arising of the modern, German building expertise involving the use of concrete, which develops during the first three quarter of the 19th century against the backdrop of a general modernisation p ...
A preliminary assessment of conditions for the industrial manufacture of a new cementitious system based on clinker-calcined clay and limestone, developed by the authors, referred as "low carbon cement" is presented. The new cement enables the substitution ...
High-performance concrete is sensitive to early-age cracking, mainly due to its rapidly-developing autogenous shrinkage. Autogenous shrinkage and internal relative humidity (RH) decrease are direct consequences of the emptying of capillary pores due to cem ...
The temperature is known to influence the strength and durability of concrete. Temperature has also a great influence on the creep of cementitious materials. Previous investigations have not provided a complete understanding of these effects; in particular ...
This paper presents the importance of microstructural studies for understanding concrete durability. Three examples-sulfate attack; alkali silica reaction and bacteriogenic corrosion in sewers arc used to illustrate the pitfalls which can arise from conven ...
We demonstrate in this poster the role played by stochasticity in bedload transport on steep slope. Multiscale and multifractal behavior is observed, while long range correlation takes place. ...
This book describes for the first time ever, the rise of the modern art of building with concrete in the different German territories stretching from Friesland to Pomerania and southwards from Bavaria to Baden during the first three quarters of the 19th ce ...
Due to the enormous volumes produced the production of concrete accounts for around 5-10% of man-made CO2 emissions. Consideration of possible routes to reduce this environmental impact indicates that the use of calcined clays in as supplementary cementiti ...
Controlled low-strength material (CLSM) mixture design remains a trial-and-error process. A new approach using relative proportioning of the constituent materials instead of prescribed mass contents is proposed. Relative proportions allow for independent a ...
Alkali-activatedslag(AAS) binders are obtained by a manufacturing process less energy-intensive than ordinary Portland cement (OPC) and involves lower greenhouse gasses emission. These alkaline cements allow the production of high mechanical strength and d ...
