Thermal and hydrothermal treatment of UHPC: influence of the process parameters on the phase composition of ultra-high performance concrete

Autor: André Gardei, Sebastian Simon, Patrick Fontana, Julia von Werder, Birgit Meng

Publikováno v: Materials and Structures. 54

Several studies show that thermal and hydrothermal treatment can further improve the excellent properties of UHPC in terms of mechanical strength and durability. While for the thermal treatment the increase in strength is attributed to an intensified

Composite Façade Elements with Self-Cleaning Surface made of UltraHigh-Performance Concrete (UHPC)

Autor: Birgit Meng, Johannes Hoppe, Patrick Fontana, Serdar Bilgin, Julia von Werder

Publikováno v: XV International Conference on Durability of Building Materials and Components. eBook of Proceedings.

In the framework of the European project H-House various concrete façade elements were developed with the aim to ensure a long service life by combining a very durable material with selfcleaning properties. The façade elements presented are made of

Autoclaving of ultra-high performance concrete (UHPC)

Autor: Sebastian Simon, Birgit Meng, Patrick Fontana, Christian Selleng, Julia von Werder, Christian Lehmann

Publikováno v: ce/papers. 2:131-136

By the combination of an optimized granulometry, a reduced water?cement ratio and the use of superplasticizers ultra-high performance concrete achieves a compressive strength of over 150 N ...

Synthesis and characterisation of alites from reduced basic oxygen furnace slags

Autor: Burkart Adamczyk, Katharina Schraut, Christian Adam, Dietmar Stephan, Birgit Meng, Sebastian Simon, Julia von Werder

Publikováno v: Cement and Concrete Research. 147:106518

Basic oxygen furnace slags (BOFS) are by-products of the steelmaking process. Several researchers have studied the production of Portland cement clinker and metallic iron from BOFS via a reductive treatment. In this study, we applied a carbothermal r

Comparative analysis of the dynamic vapor sorption (DVS) technique and the traditional method for sorption isotherms determination — Exemplified at autoclaved aerated concrete samples of four density classes

Autor: Julia von Werder, Magdalena Bochenek, Winfried Malorny, Halina Garbalińska

Publikováno v: Cement and Concrete Research. 91:97-105

The paper assesses two research techniques for the determination of moisture sorption isotherms. On the one hand, in the time and labor-intensive traditional method the relative humidities are set in desiccators or climatic chambers by saturated wate

Application of fluorometric and numerical analysis for assessing the algal resistance of external thermal insulation composite systems

Autor: Julia von Werder, Robert Černý, Helmuth Venzmer

Publikováno v: Journal of Building Physics. 38:290-316

As a consequence of the reduced transmission heat loss, algal growth on external thermal insulation composite systems has given rise to a serious aesthetical problem over the last decade. Manufacturers of paints and rendering systems are competing to

Algal defacement of facade materials – results of long-term natural weathering tests obtained by new diagnostic tools

Autor: Julia von Werder, Helmuth Venzmer, Natalia Lesnych, Lev Koss

The growth of algae on facade materials has developed to a serious, primarily aesthetical problem over the last decade. Responsible for the substantial increase in biologically soiled facades is the extended presence of humidity films on the building
