The scope of this study was to investigate the carbonation of waste disposal facility concrete. The effects of the silo concrete mixture on the physical properties of concrete and the alteration of the microstructure of the cement paste due to exposure to carbon dioxide were included in this investigation.

Chloride Attack

The concrete life was shown very differently according to the conditions surrounding the structure. Because the silo concrete structure (waste disposal facility) is geomorphologically located to underground-130m below at coast, the chloride injury rather than freezing and thawing as the more important factor for the service life evaluation. In this study, the service life of silo concrete was evaluated based on the results of chloride attack

This paper provides a critical review of the degradation, durability and service life prediction (SLP) of polymeric building envelope materials (BEMs), namely, claddings, air/vapour barriers, insulations, sealants, gaskets and fenestration. The rate of material deterioration and properties determine the usefulness of a product; therefore, knowledge of the significant degradation mechanisms in play for BEMs is key to the design of proper SLP methods. SLP seeks to estimate the life expectancy of a material/component exposed to in-service conditions. This topic is especially important with respect to the potential impacts of climate change. The surrounding environment of a building dictates the degradation mechanisms in play, and as climate change progresses, material aging conditions become more unpredictable. This can result in unexpected changes and/or damages to BEMs, and shorter than expected SL. The development of more comprehensive SLP methods is economically and environmentally sound, and it will provide more confidence, comfort and safety to all building users. The goal of this paper is to review the existing literature in order to identify the knowledge gaps and provide suggestions to address these gaps in light of the rapidly evolving climate.
