Welcome to SaltWiki

SaltWiki is intended to share current specialist information on salts, damages caused by salts and dealing with salt damage. You are welcome to contribute to this joint venture and to collaborate in compiling SaltWiki as an author. Information about the project you find here.

After completing the DFG project, the research group has founded the association SIK who has been committed to update the contents. The Hornemann Institute of the HAWK is responsible for the technical and graphical maintenance of the portal.

CRYSPOM VII / 3-5 June 2020 in Pau (France)

The Biannual International workshop Crystallization in Porous Media CRYSPOM focuses on fundamental research of crystallization in porous materials. It unites researchers from geoengineering, geology, physics, chemistry, mechanics and conservation interested in crystal nucleation, growth and transport in porous media and its related consequences.

The idea is to bring together leading researchers and Ph.D. students to provide for a constructive and open dialogue. Also, it seeks to incite collaborations between theorists, modelists and experimentalists on an international level.

CRYSPOM results from a long-standing tradition. The workshop was founded by Prof. Noushine Shahidzadeh in 2008 in Paris, and subsequently took place in Brienz (Switzerland, 2010), Troia (Portugal, 2012), Amsterdam (The Netherlands, 2014), Toulouse (France, 2016) and Hamburg (Germany, 2018). The seventh in the series will be held in Pau (France), 3-5 June 2020.

Topics of interest include, but are not limited to:

  • Fundamentals of crystallization in porous or confined media
  • Coupled problems including crystallization
  • Crystallization in the built environment
  • Crystallization and rock transformation in nature
  • Crystallization of salt and gas hydrates

Abstract submission is now open, registration will open beginning of 2020. The registration fee (including conference bag, printed booklet, lunches and refreshments and conference dinner) will be 250 €.
