Influence of Organic Content on the Mechanical Properties of Organic-Rich Soils Stabilized with CaO-GGBS Binder and PC

Organic-rich soil is a typical special often encountered in foundation treatment. Previous research has revealed that Portland cement (PC) not only pollutes the environment but significantly affected by organic matter during its hydration and cementation. Although quicklime (CaO)-GGBS binder (CG) an effective alternative to PC, efficiency treating organic-rich soils been studied. In this study, was treated with two binders of CG PC. The physical, mechanical, chemical characteristics stabilized were tested at various contents, curing ages. results show cracks increase content reduction content. CG-treated are more likely shed big lumps after damage than PC-treated soils. unconfined compressive strength (qu) deformation modulus (E50) increasing age decreasing E50 about 22~73 times qu, shows excellent linear relationship qu. moisture increases as grows, it falls increase. pH rises content, declines increased age. development evident attenuation Given possible environmental benefit, alkali (especially low calcium)-activated appropriate for practical engineering modest needs.
