Volcanic ash in the atmosphere
, 2019 This thesis presents new work on the characterisation of volcanic ash in the atmosphere. The eruption of Eyjafjallajökull in 2010 brought the issue of ash in the atmosphere into sharp focus. Radiative transfer models used in remote sensing and hazard assessment of volcanic ash require knowledge of ash optical parameters, which are governed by the ...

Volcanic ash (VA) is a natural resource whose use in cementitious materials has been extensively studied in the last thirty years. The pozzolanic activity makes the volcanic product suitable for use as supplementary cementitious material in concrete. However not all ashes possess this reactivity in their natural state.
