2023.7.1 The advantage of soil stabilization is an increase in soil strength, durability, stiffness, and a decrease in soil plasticity and possible swelling/shrinking [85]. At high temperatures, limestone decomposes to generate lime [61] There are consequently three types of lime that may be used to remediate soil: quicklime (calcium oxide, CaO),
