Guest post: Pyrite oxidation in roofing slates by Víctor Cárdenes Van den Eynde

The first guest post on pyriteproblem.com comes from Dr. Víctor Cárdenes Van den Eynde. Victor started his career in the slate industry of Galicia (Spain), later moving to the Slate Technology Center Foundation (Galician Association of Slate Producers). There, he developed various methods of inhibiting oxidation of iron sulfides in roofing slates.

He later moved to the University of Oviedo, working as a reseacher and completing a Masters in Geological and Geotechnical Resources in 2010 and a PhD in roofing slate in 2012. He currently researches the petrophysics and weathering of building materials. Further information about Victor’s research and publications can be found at the end of this post.… Read the rest

Research paper: Lime stabilisation for earthworks: a UK perspective

Lime Stabilisation in the UK

Paul Beetham (Loughborough University), Tom Dijkstra (BGS), Neil Dixon (Loughborough University), Paul Fleming (Loughborough University), Robert Hutchison (Opus) and John Bateman (Independent consultant) have published a review paper on the application of lime stabilisation in UK earthworks.

The paper, titled “Lime stabilisation for earthworks: a UK perspective” considers the chemistry of the lime stabilisation process and the implications of the minimum mellowing period and air voids. The role of sulfate swelling in lime stabilised materials and how the risk of the this may be reduced is also discussed. The full abstract from the ICE Proceedings: Ground Improvement is shown below.… Read the rest
