Fly ash as an assemblage of model Ca-Mg-Na-aluminosilicate glasses

Karen Scrivener, Ruben Anton Snellings, Cyrille Dunant, Mohsen Ben Haha, Pawel Tadeusz Durdzinski

Model Ca-Mg-Na-aluminosilicate glasses based on compositions found in a calcareous fly ash were synthesised and their reactivity assessed in NaOH solution and in Portland cement paste. It was found that the reactivity followed the same trend in both system ...

Understanding the Filler Effect on the Nucleation and Growth of C-S-H

Karen Scrivener, Elise Marie Jeanne Berodier

The filler effect, due to the physical presence of mineral additions in cement, is mainly known to accelerate the hydration of the clinker component. Previously, this was attributed to the surface of the filler providing nucleation sites for C-S-H as there ...

Four-dimensional distribution of the 2010 Eyjafjallajokull volcanic cloud over Europe observed by EARLINET

Valentin Simeonov, Ilya Serikov, Ivan Videnov Grigorov, Xiao Wang, Frank Rüdiger Wagner, Valentin Mitev

The eruption of the Icelandic volcano Eyjafjallajokull in April-May 2010 represents a "natural experiment" to study the impact of volcanic emissions on a continental scale. For the first time, quantitative data about the presence, altitude, and layering of ...

Early warning thresholds for partially saturated slopes in volcanic ashes

Lyesse Laloui, Alessio Ferrari, John Eichenberger

Rainfall-induced landslides in steep soil slopes of volcanic origin are a major threat to human lives and infrastructure. In the context of constructing early warning systems in regions where extensive data on landslide occurrences and associated rainfall ...

Hydro-mechanical behaviour of a volcanic ash

Lyesse Laloui, Alessio Ferrari, John Eichenberger

This paper presents experimental analysis and numerical modelling aimed at improved understanding and prediction of the hydro-mechanical behaviour of volcanic ash at various states of saturation. Results from a comprehensive experimental program are presen ...

On the relationship between total ozone and atmospheric dynamics and chemistry at mid-latitudes - Part 2: The effects of the El Nino/Southern Oscillation, volcanic eruptions and contributions of atmospheric dynamics and chemistry to long-term total ozone changes

Anthony Christopher Davison, Linda Frossard

We present the first spatial analysis of "fingerprints" of the El Nino/Southern Oscillation (ENSO) and atmospheric aerosol load after major volcanic eruptions (El Chichon and Mt. Pinatubo) in extreme low and high (termed ELOs and EHOs, respectively) and me ...

Experimental and numerical analysis of an unsaturated volcanic ash deposit for the establishment of an early warning system in a quarry in Costa Rica

Lyesse Laloui, Alessio Ferrari, John Eichenberger, Elliot James Fern

The paper presents the work carried out for the analysis of the hydro-mechanical behaviour of a volcanic ash in unsaturated conditions for the establishment of a landslide eary warning system (EWS) in a Costa Rican quarry. Rapid mass movements involving as ...

Diffusive-type of double diffusion in lakes - a review

Alfred Johny Wüest, Martin Schmid

This chapter is a contribution in honour of Gerhard H Jirka, who has been fascinated by the amazing variety of small-scale structures that nature surprises us with, particularly in stratified natural waters. Here, we focus on the diffusive regime of double ...

Hygroscopic properties of volcanic ash

Athanasios Nenes

Limited observational data exists on the physical interactions between volcanic ash particles and water vapor; yet it is thought that these interactions can strongly impact the microphysical evolution of ash, with implications for its atmospheric lifetime ...
