Proposals have been made by several researchers to conduct the sequestration of carbon dioxide (CO) through calcium and magnesium-rich materials. From these materials, ground granulated blast furnace slag (GGBS) containing 5% magnesium and 45% calcium is seen to be a good candidate and is available to sequester CO. This study intends to ascertain the ability to absorb CO, sequester it, and increase treated kaolin strength with different content of GGBS under various carbonation periods with varying CO pressure.

This paper reviews and discusses the ground improvement and its contribution to reducing CO in the atmosphere. The approach is divided into three parts: the Streamlined Energy and Emissions Assessment Model (SEEAM), the replacement of soil stabilisation materials that lead to the emission of a large amount of CO with alternatives and mineral carbonation.

In civil engineering, many geotechnical and forensic projects employ polyurethane (PU) for ground improvement, and the results have shown to be effective in terms of time and cost savings. However, similar to many other chemical stabilisers, the use of PU for soil stabilisation may have environmental repercussions. Therefore, this paper utilised a toxicity characteristic leaching procedure (TCLP) to investigate the potential for ground contamination resulting from the application of PU for the stabilisation of marine clay.
