Abstract: Over the last decade there has been a steady focus on research projects gearing towards sustainable development. This includes sustainable building and green concrete. Many Asian countries are still experiencing growth in the construction industry due to rapid development of infrastructure. This implies construction of new buildings and demolition of old ones.
Singapore is presently experiencing a phase of rapid growth in the construction industry, which generates a large amount of concrete waste. On the other hand, Singapore is facing a shortage of natural aggregates and also scarcity of landfills for disposing the wastes from old construction works. Therefore, it is increasingly attractive from an economic and environmental point of view to recycle old concrete aggregates.
In this investigation, physical, chemical and mechanical properties of natural aggregates (NA) and recycled concrete aggregates (RCA) have been investigated. The study also included the mechanical and microstructure properties of several concrete mixes comprising different percentages of recycled concrete coarse aggregates to investigate the potential of using RCA as a source for producing new concrete in Singapore.
