Carbonated ground granulated blast furnace slag stabilising brown kaolin.

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.
