Abstract
To investigate the mechanical properties of Fiber Bubble Lightweight Mixed Soil(FBLMS),this study system-atically examined the effects of its constituent dosages—namely,cement,fiber,water,bubbles,and admix-tures—on its performance using unconfined compressive testing.The findings indicate that it increases with higher dosages of cement and slag powder,while it decreases with greater amounts of water,bubbles,and fly ash,exceeding this threshold to 0.3％or more reduces the material's strength.The deformation characteristics under unconfined compression are also dosage-dependent.A higher cement content reduces the material's failure strain,shifting the soil sample's failure mode from ductile to brittle.In contrast,increasing the fiber,water,and bubble dosages improves the failure strain,thereby promoting a shift from a brittle to a ductile fail-ure mode.关键词
