Field Test Results of Palm Oil Clinker Concrete Pile and Foamed Concrete Pile for Floating Foundation in Soft Soil

摘要

The typical properties of Lightweight Concrete Pile (LCP) are low density, low strength and high porosity. Such inherent properties made use of LCP for deep foundation are still rare. In spite of Normal Concrete Pile (NCP) has been widely used in civil engineering industry, the use of LCP such as palm oil clinker concrete pile (p-LCP) and foamed concrete pile (f-LCP) for floating foundation must be verified. The purpose of this study was to perform the static and dynamic load tests for assessing the performance of p-LCP and f-LCP and that of NCP as reference. The physical characteristics of either p-LCP or f-LCP have higher average values of compressive stress and driving resistance comparing with NCP. Features of good performance for p-LCP and f-LCP can be used for deep foundation of particular structures in soft soil and were verified to contribute to material and structural perspectives for the future of geotechnical engineering.
