Implications Of Pyrite Oxidation For Engineering Works

Download or read book Implications of Pyrite Oxidation for Engineering Works written by A. Brian Hawkins and published by Springer Science & Business Media. This book was released on 2013-07-30 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book highlights and analyses the distress to buildings caused by sulphate-induced heave, with particular reference to the recent problems in the Dublin area of Ireland. It describes the formation of pyrite, the processes involved in its oxidation and the various ways in which consequential expansion takes place. For the first time in the literature it discusses the way that buildings can be raised above their supporting foundation walls by the expansion of pyritiferous fill which has been used beneath ground-bearing floor slabs in Ireland. The significance of fractures through the iron sulphide microcrystals for the rate and extent of oxidation is discussed. Photographs and profiles of sulphate ingress into concrete/concrete blocks are presented. Case histories from the UK, North America and Ireland are discussed.
