Thermomechanical characterization of a balsa-wood-veneer structural sandwich core material at elevated temperatures

Thomas Keller, Anastasios Vassilopoulos, Chao Wu, Niloufar Vahedi

The tensile, compressive and shear behavior of standardized specimens cut from a veneered balsa wood used as structural sandwich core was investigated at ambient temperatures of up to 250 degrees C. The average moisture content was 9.1%. The specimens' res ...

Hydration of multi-component cements containing cement clinker, slag, calcareous fly ash and limestone

Pawel Tadeusz Durdzinski

Calcareous fly ashes are high-potential reactive supplementary cementitious materials, which present an interesting alternative to slowly reacting siliceous fly ashes and to slags, which availability is more and more limited. Themain factor against an accu ...

Thermal treatment of metal-enriched biomass produced from heavy metal phytoextraction

Christian Ludwig, Catherine Keller

Phytoextraction is an environmentally sound method for cleaning up sites that are contaminated with toxic heavy metals. However, the method has been questioned because it produces a biomass-rich secondary waste containing the extracted metals. Therefore, f ...
