sulfate generated heave
Peter Finnegan (Dublin City Council), Paul Forde (DBFL Engineers) and Brian Hawkins (Engineering Geological Consultant) have published a paper on the structural effects of sulfate generated heave, with particular reference to the problems in Dublin, Ireland.
The paper, titled “Sulphate-generated heave – the effect on structures in Dublin” adds to existing information published by the authors in their respective chapters of the 2013 book, Implications of Pyrite Oxidation for Engineering Works. Finnegan et al (2014) describe the typical mechanisms and types of damage that can occur due to expansion of sub-floor aggregate. The authors also discuss methods and planning of remediation, including consideration of the potential for differential stresses in adjacent structures during remediation.… Read the rest
