Effect of calcium content on soil stabilisation with alkaline activation
TL;DR: In this article, the role of calcium content in fly ash used to stabilise soft soils through alkaline activation with sodium-based alkaline activators was concerned with the role and role of fly ash type C, with higher calcium content (FAC), and type F, with lower calcium content(FAF) were used separately, and soil-cement and soillime (SL) mixtures were also tested.
