Determination of the geochemical weathering indices and trace elements content of new volcanic ash deposits from Mt. Talang (West Sumatra) Indonesia Universiteit Gent
Assessment of the potential for in-plume sulphur dioxide gas-ash interactions to influence the respiratory toxicity of volcanic ash Vrije Universiteit Brussel
Background: Volcanic plumes are complex environments composed of gases and ash particles, where chemical and physical processes occur at different temperature and compositional regimes. Commonly, soluble sulphate- and chloride-bearing salts are formed on ash as gases interact with ash surfaces. Exposure to respirable volcanic ash following an eruption is potentially a significant health concern. The impact of such gas-ash interactions on ash ...
Development of a simulated lung fluid leaching method to assess the release of potentially toxic elements from volcanic ash KU Leuven Vrije Universiteit Brussel
Vertical profiling of volcanic ash from the 2011 Puyehue Cordón Caulle eruption using IASI Universiteit Gent
Influence of the activating solution composition on the stability andthermo-mechanical properties of inorganic polymers (geopolymers)from volcanic ash Vrije Universiteit Brussel
The samples are cured at 90°C and the mechanical strength increases up to 21days. With NaOH the strength development is faster, with a dry and wet compressive strength respectively around 40 MPa and ...
Charge fingerprint in relation to mineralogical composition of Quaternary volcanic ash along a climatic gradient on Java Island, Indonesia Universiteit Gent
Controls on iron mobilisation from volcanic ash at low pH: Insights from dissolution experiments and Mossbauer spectroscopy KU Leuven
Properties of alkali activated lightweight aggregate generated from Sidoarjo volcanic mud (Lusi), fly ash, and municipal solid waste incineration bottom ash Universiteit Gent
Assessment of leachable elements in volcanic ashfall: A review and evaluation of a standardized protocol for ash hazard characterization Vrije Universiteit Brussel
Volcanic ash presents a widespread and common hazard during and after eruptions. Complex interactions between solid ash surfaces and volcanic gases lead to the formation of soluble salts that may be mobilized in aqueous environments. A variety of stakeholders may be concerned about the effects of ash on human and animal health, drinking water supplies, crops, soils and surface runoff. As part of the immediate emergency response, rapid ...
