Compressive and Shear Strengths of Coir Fibre Reinforced Activated Carbon Stabilised Lateritic Soil

Constructing structures on lateritic soil is challenging in geotechnical engineering due to the various physical and characteristics. Many studies investigated different stabiliser materials strengthen parameters of soil. This study used activated carbon coir fibre (ACF) stabilise soils as an environmentally friendly binder. Experiments including unconfined compressive strength (UCS) test direct shear (DST) are performed investigate mechanical properties ACF-stabilised for percentages (AC). Before after ACF stabilisation, microstructural characterisations samples were using field emission scanning electron microscopy (FESEM) surface-area analysis (BET). The experimental results demonstrate that 3% can considerably enhance strength, while 2% significantly improves Accordant UCS results, AC-stabilised post-peak behaviour residual strength. Moreover, improve by creating interlocking matrix among AC, particles, fibre. characterisation based findings obtained FESEM BET confirms AC particles fill voids. restrains movement when exposed external stresses. In addition, formation gel stabilised binds increasing comparison with untreated
