Compressibility behaviour on carbonation of ground granulated blast furnace slag (GGBS) treated kaolin

The mounting concerns, with regards to environmental contamination, have led to the need for a better un-derstanding of carbon oxide emissions. The escalation in economic activities, as well as the rapid global popu-lation growth, has contributed towards a detrimental impact on the environment. This study delves into the curbing of carbon dioxide emissions, particularly in the context of the construction industry, using sustainable materials. The emphasis, of this investigation, is on the effect of carbonation, on the compressibility behaviour, of ground granulated blast furnace slag (GGBS)-treated kaolin clay. According to the results derived from a one-dimensional consolidation test, the compressibility attributes improved in tandem with the GGBS content. Generally, these results indicate that a greater GGBS content, and a prolonged curing time, gives rise to less compressibility behaviour of treated kaolin clay. It was also revealed that in comparison to the treated kaolin sample, the carbonated kaolin sample delivered a greater degree of compressibility. Thus, it can be surmised, that carbonation enhances the compressibility features of kaolin.

Automated summary

The increasing concerns about environmental contamination have raised the need for a better understanding of carbon dioxide emissions. The impact of economic activities and global population growth has negatively affected the environment. This study focuses on reducing carbon dioxide emissions in the construction industry through the use of sustainable materials. The research shows that the compressibility behavior of kaolin clay treated with ground granulated blast furnace slag (GGBS) improves with higher GGBS content and longer curing time. It also reveals that carbonation enhances the compressibility features of kaolin clay.
