Modification of soft soils with ground granulated blastfurnace slags with activated magnesium oxide

Portland cement (PC) is commonly used material in soil stabilisation treatment. However, with the rise of environmental consciousness, more environmentally friendly industrial by products have been used and investigated to replace PC. This paper addresses the use of ground granulated blast furnace s...
