Predicting Concrete Service Life in Climate Zones of Iran

The durability of materials is the critical element in determining the service life of concrete systems,and hence, it contributes to the sustainability and resilience of lifelines and core infrastructures utilizingconcrete. The rise in disasters due to climate change has required a paradigm shift in engineering design toimplement quantitative sustainability, objective resilience, and health, safety, and welfare performancemeasures. This presented study aims to assess the performance of concrete materials in ۸ different casesinvolving different applications and climate zones. Selected applications involve different levels ofenvironmental exposures, including parking garages, bridge decks, and ports. Climate zones includepredefined characteristics of dry versus wet and freeze versus no-freeze regions. The analyticalmethodology relies on service life prediction modeling to quantify the influence of the climate and theenvironment using Life-۳۶۵TM. Comparative evaluation of lifecycle measures like cost, energy, andemissions are mapped with sustainability rating measures in Envision. The results of this study highlightthe sensitivity of presented evaluations to climate zone characteristics and provide insights on drafting theroadmap to implement climate change in practical engineering guidelines
