Quantitative Considerations of Moisture as a Climatic Factor in Weathering

Abstract
Following the concept of the solar weathering index which is a climatic parameter for physical damage functions that quantify photo-oxidation of organic building materials, functions that relate to moisture associated degradation of building materials have been considered. These have involved studies where some quantatitave information has been given on both exposure and effect, such as atmospheric corrosion of metals, chalking of paints, photo-oxidation of polyester resins and strength loss in timber composites. The pertinent moisture parameters have been discussed and where possible evaluated for Australian sites from meteorological data. Several new climatic parameters have been suggested and further work on validating these as factors in physical damage functions suggested.
