Zum Einfluss der Wechselwirkung zwischen Schalmaterial, Trennmittel und Beton auf die Eigenschaften von Sichtbetonflächen
(2018)
Sichtbetonflächen unterliegen hohen Anforderungen an das Erscheinungsbild. So soll die Farbgebung gleichmäßig und die Oberfläche porenarm sein - dabei variieren die Anfor-derungen mit der geforderten Sichtbetonklasse. Dies erfordert ein hohes Maß an Können bei der Herstellung sowie dezidierte Kenntnisse über Leistungsfähigkeit und Wechselwirkungen der eingesetzten Materialien. Die Erfahrungen aus der Praxis zeigen jedoch, dass die gezielte und gleichmäßige Herstellung von Sichtbetonflächen schwierig ist. Ziel dieser ...

Virtual portfolios for earthquake insurance related risk simulations
(2018-04-05)
Seismic Risk, a combination of Hazard, Vulnerability and Loss, is becoming a mainstream topic due to an increase in the losses and damage caused by earthquake related effects worldwide.
Therefore, it has become an important aspect for insurer and reinsurers since it is extremely difficult to assess due to the lack of the necessary data compared, for example, to car insurance (chapter 1). As described in chapter 2, where the state of the art of seismic risk assessment and simulation is described alongside a more ...

Design procedure for shear panels and their connections in Hysteretic Device Systems
(2018-07)
Every year, earthquakes kill thousends of people and destroy or damage many buildings and structures worldwide. It was observed that the damages induced by earthquakes in developed countries (e.g., Japan and the USA) are less when compared to less developed countries such as Iran, Turkey or Pakistan. Comparing the earthquake damages indicated that even in new and modern buildings, some problems can be seen facing large earthquakes.
Every earthquake has proved the vulnerability of many structures to damages. A lot ...

Influence of Calcium Aluminate Cement and Ground Granulated Blast Furnace Slag on the Synthesis of Rice Husk Ash-Based Geopolymer Mortars
(2018-02-26)
The manufacture of Portland cement is energy intensive and is associated with carbon dioxide emission of approximately 7% of total global emission. The process also produces pollution in the forms of dust, noise, and vibration with operating machinery during blasting in quarries. Geopolymer material is formed through the reaction of silica and alumina oxides with alkali activator and has appeared as a viable alternative to the Portland cement in the construction field due to good properties such as high compressive, ...
