This study aims to highlight the effect of fibre–clay contact area in a fibre-reinforced clay matrix with different fibre contents and types. Fibre-reinforced samples were prepared at two compaction densities (1600 and 1800 kg/m3) using four fibre types (i.e. basalt, carbon, polypropylene and glass) with five fibre contents of 0.1–0.5%. A series of unconfined compressive […]
