As some types of fly ash show high potential for CO2 sequestration (e.g. co-combustion fly ash), the use of carbonated fly ash could also help with the reduction of carbon emissions in the construction sector. This paper presents the results of LCA study that compared the environmental impacts associated with the construction of an embankment using carbonated cocombustion fly ash and conventional construction material (i.e. soil). The cocombustion fly ash was carbonated naturally, which eliminated the environmental impacts related to the accelerated carbonation, such as capturing and supply of CO2, and energy consumption for the carbonation process. Results show that the use of carbonated co-combustion fly ash for embankment construction has several environmental advantages compared to the construction with soil, such as lower impact associated with the transport of material, environmental benefit associated with the avoided landfilling and reduction in the carbon footprint due to the natural CO2 sequestrationSpringer20262026-06-18 11:36:49Neznano30289sl
