Report BR 325 Sulfide-related degradation of concrete in Southwest England ('The Mundic Problem')
Publication Year
1997
Document Status

Abstract
Following the decline in the use of natural stone at the beginning of this century, most domestic and small commercial properties in Cornwall and South Devon were built with concrete blocks and mass concrete using local sand and coarse aggregate, available as waste materials from the region's metalliferous mining industry. Some wastes proved to be very unstable in service, sometimes necessitating demolition of properties. This is known locally as 'the Mundic problem', Mundic being the old Cornish-Celtic word for pyrite, which is abundant in many mining wastes and is central to the degradation process. This report gives an overview of the problem, giving details from tests of samples taken from numerous properties.
