Stabilization of high water content clay using carbonized cow dung compost / calcined oyster shell and application of simple dry distillation gasifier
Stabilization of high water content clay using carbonized cow dung compost / calcined oyster shell and application of simple dry distillation gasifier
This study proposes a geotechnical utilization of calcined waste oyster shells (COS) and carbonized cow dung compost (CC) instead of cement for stabilizing clay with high-water content. A comparison with commercial wood charcoal proved that CC with better adsorption capacity significantly improved high-water-content clay. COS has the potential to stabilize high water-content clay. Cone penetration tests was performed to investigate the mechanical property of the stabilized clay. Mixing of CC with a high-water absorption rate showed the improvement effect of COS-stabilized clay. The applicability of a mixture of cow dung and waste plastic by dry distillation gas generated from organic matter is also confirmed. When an appropriate amount of plastic is mixed with cow dung compost, it burns stably, the combustion temperature reaches 700 or higher, and a carbonized material with a temperature of around 600 is obtained. From the test results, it was confirmed that the carbonized material of cow dung compost will be used as good material in geo-environmental field.
