Sustainable cementitious blends for strength enhancement of dredged mud in Queensland, Australia

Cement is commonly used as a stabilisation material in soft soil stabilisation. However, the use of cement can cause environmental issues, production results high emission carbon dioxide (CO 2 ). Hence, it essential to develop other suitable materials reduce amount soil. Fly ash and DuraCrete (blended cement) were investigated this study be partial replacements for traditional cement-only mixes. The behaviour specimens stabilised using cement, fly under both unconfined compressive consolidated isotropic undrained conditions was study. experimental proved that cement. provide highest reduction terms percentage Meanwhile, more cost effective, relatively smaller quantity replace correspondingly larger similar strength gain. contribution research engineers with alternative, sustainable design mixes readily satisfy requirements while emitting less dioxide.
