Abstract

Today, cement is one of the most popular materials used in geotechnical engineering projects because of its excellent soil stabilizing properties. The big concern, however, is that its production results in the emission of a large amount of carbon dioxide (CO2) which contributes to the cumulative CO2released worldwide which is recognised as one of the main contributing factors to climate change and the greenhouse gas effect, which results in global warming. Olivine with chemical formula (Fe,Mg)2SiO4 is a suitable mineral for CO2 sequestration; additionally due to its high Magnesium oxide (MgO) content, it may be a sustainable material for soil stabilization. The chemical combination of Olivine categorizes this mineral in the class of pozzolans. Magnesium oxide has a high potential for CO2 capturing and carbonated magnesia provides stability in soil and is thus an active layer in works on stabilizing slopes against sliding.
