Project Description:
This research addresses environmental concerns associated with conventional concrete by proposing an innovative sustainable alternative. Seawater and sea sand, known substitutes for freshwater and river sand, are combined with rubber aggregates to create a novel concrete mix. While seawater sea sand concrete and rubberised concrete have been individually studied, their combined potential remains largely unexplored. By incorporating waste rubber as a partial replacement for traditional aggregates, we not only contribute to environmental sustainability but also enhance the ductility and energy absorption capacity of concrete.
The project highlights the need for a sustainable solution by integrating these materials. The proposed concrete will be confined using stainless steel and fiber-reinforced polymer tubes in single and double skin schemes to mitigate potential shortcomings. An experimental plan is outlined to evaluate the axial performance of innovative columns, considering challenges such as corrosion in seawater sea sand concrete and reduced compressive strength in rubberised concrete. The research aims to contribute valuable insights for recommending these innovative columns in coastal and marine infrastructure, addressing the demand for high ductility in such environments.
