Abstract
Purpose
The purpose of this paper is to demonstrate the effect of accelerated environmental loading, i.e. humidity, solar radiation, wet/dry cycling, CO2 concentration and temperature on specimens being initially protected using 4 commercially available coating systems and to evaluate their degradation considering the results.
Design/methodology/approach
For the purpose of the study, an accelerated environmental loading was performed in a highly sophisticated chamber able to replicate weather patterns representing the 8 characteristic climate zones of Australia.
Findings
The results in terms of degradation patterns can provide a qualitative classification leading to the development of a Dynamic Protection Index Factor (DPIF) which can be used as direct input in life cycle cost analysis appraisal.
Originality/value
This paper is considered to be very important, since the degradation results of different environmental conditions constiture a major problem for structures life inspections and durability
