| Summary: | Ground improvement using cement as a binder to improve the strength and stiffuess of the soft soil (e.g. peat, alluvium deposits and silty sand) to prevent any ground water ingress has been widely used in the current subsurface excavation works such as tunnelling, underpass, basement excavation and others. The strength and elastic modulus of the grouted soils have been determined by classical destructive methods. However, the performance of grouted soft soils depends on several parameters such as the distribution of the particulate soil media, grouting pressure, grouting rotation, amount of cement and ground water flow. In this study, we are going to research on the correlation between the Unconfmed Compressive Strength of the mixed soil with the Standard Penetration Test and Young Modulus. This research will comprise of the concept of ground improvement using enhanced jet grouting called wet speed mixing method, construction methodology, coring test to determine the compressive strength and Young's Modulus criteria and standard penetration test. |
