Compressibility of Fly Ash and Fly Ash-Bentonite Mixtures
The Baltic Journal of Road and Bridge Engineering, 2022 Environmental protection, one of the most important issues nowadays, forces civil engineers to look for alternative solutions to the known ones. The use of substitute materials as an embankment fill or a ground material under the embankment instead of natural soil follows these trends. A great amount of fly ash is disposed of in landfills. It is a cost-
