Degradation analysis by accelerated ageing of epoxy based mortar as used in the Metropolitan Cathedral

The Liverpool Metropolitan Cathedral is the Roman Catholic Cathedral in Liverpool. It was constructed between 1962 and 1967. The roof of the building is crowned by a tapering lantern formed from coloured glass adhered by means of an epoxy-based mortar.  Soon after opening leaks were observed through the glazed lantern between the epoxy and the glass.

The goal of this research project is to get an idea of the life expectancy of the epoxy mortar used for building and construction of the Lantern of the Liverpool Metropolitan Cathedral. For this research the original epoxy-mortar formulation will be replicated. This replica mortar as well as the original mortar core samples will be used to undertake accelerated ageing tests (e.g. by moisture, UV exposure and elevated temperature). The generated data will indicate the likelihood of possible loss of the structural integrity of the mortar which might endanger the lantern structure.
