Geotechnical and microstructural properties of EICP-treated coal char-modified expansive soils
Enzyme-induced carbonate precipitation (EICP) is an innovative soil stabilization method, though its performance can be limited by insufficient nucleation sites and uneven calcite distribution. This study investigates the use of coal-derived char as an additive in EICP-treated sodium bentonite-sand mixtures to improve...
