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 geotechnical characteristics. Many studies investigated different stabiliser materials to strengthen the geotechnical parameters of lateritic soil. This study used activated carbon an...
