Abstract

When exposed to persistent moisture fluctuations, expansive clayey soil is mostly impermeable and has a dual tendency (swelling/shrinkage). The heave motion causes such clayey soils to lose volumetric and mechanical strength and is difficult to regulate the differential settlement. The current study focuses on the stability of black expansive clayey soil (BES) using alkaline-activator binders (ABs) reinforced with natural and artificial fibers instead of standard cement-based binders. The effects of different concentrations of ABs at varying curing durations are examined by conducting a series of index and shear strength property tests on treated BES. The treatment improves the geoengineering behavior of BES and helps to increase the unconfined compressive strength (UCS) values by regulating the heave and void ratios effectively. Mineral alteration caused by BES treatment with AB is responsible for reducing volumetric swelling and plasticity index. This study could be very useful in developing a cost-effective solution to the problem associated with BES.
