Mechanical and physical properties and cyclic swell-shrink behaviour of expansive clay improved by recycled glass

The stabilisation of expansive clay subgrades using recycled glass (RG) was proposed, as a sustainable ground improvement technique. Previous studies mainly focused on RG powder with contents up to 10%, while the current study utilised sand-size particles and 40% content. Physical properties, compressibility, strength characteristics, long-term climatic effects volumetric behaviour stabilised were investigated. Volumetric responses analysed through constitutive model developed for environmentally clay. experimental results revealed that plasticity mixtures decreased by 30% content increased 40%. By larger particles, bearing capacity about 45% 130% addition 25% RG. However, adding 6% sufficient increase 100% 200%, respectively. swell-shrink suggested maximum swelling achieved in second cycle which classification converted from medium high also compared discussed corresponding data collected literature. outcomes this advance prediction understanding mechanical RG-stabilised
