  3. Abstract:
  4. Floating urbanization could be the subject of a green flood mitigation strategy. The main part of any floating house is the buoyant part, which is made from concrete pontoons. Aggregates play the most important role in making concrete a lightweight material. Oil Palm Shell (OPS) is an agricultural waste material, which is widely available in South East Asia. This study tries to select the best cementing material from waste and produced pozzolans, to improve the specifications of green lightweight concrete with Oil Palm Shell (OPS), using decision-making methods. The decision making model was conducted by the application of a Fuzzy Preference Selection Index (PSI). Quantitative data was obtained from laboratory testing, which was translated into fuzzy functions, and qualitative data was obtained through verbal interviews. Silica Fume (SF) contributed the best performance of all pozzolans, with a 25% replacement in green lightweight concrete, with Oil Palm Shell (OPS)
