| Summary: | Rapid globalization and urbanization has caused a need for Singapore to cut costs on construction and land reclamation materials such as sand. There is also a need to ease the difficulties encountered in waste management, as there is limited space in our landfills. The objective of this report is hence to determine if marine clay, after treatment, is suitable to replace sand in construction and land reclamation activities.
It was determined that 75% replacement of sand by treated marine clay is most suitable to address the stated objectives, and it had a compressive strength of 23.6 N/mm2, which is suitable for structural works that does not require high strength. In addition, Marine clay does not pose any threat to the environment as it TCLP results are well below allowable limits in Singapore. Therefore, with proper treatment, it was concluded that marine clay is suitable to replace sand for both construction and land reclamation activities in Singapore. |
