South Korea has a soft ground in many areas, and many reinforcing method were used to build the structure on the soft ground. PF method is eco-friendly and secure a bearing capacity by forming a basis of bulbs through mixing the soil and a high-performance "Bindearth", and can control the settlement. Here are we introduce a test case study method through the recent case of the PF.

As a fundamental analysis, this study measured and examined the mechanical property and chemical attack resistance of ceramic binder repair material at a development step through continued research. The study showed the compressive strength and bond strength of the repair material meet the standard; however, bending strength of it failed to meet the required standard. Meanwhile, chemical attack resistance displayed the excellent result.
