Mechanical Properties of Cement-Treated Soil Mixed with Cellulose Nanofibre
Cellulose nanofibre (CNF), a material composed of ultrafine fibres of wood cellulose fibrillated to nano-order level, is expected to be widely used because of its excellent properties. However, in the field of geotechnical engineering, almost no progress has been made in the development of technique...
