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

Abstract

The mounting concerns, with regards to environmental contamination, have led to the need for a better understanding of carbon oxide emissions. The escalation in economic activities, as well as the rapid global population 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.
