Green Concrete: Recycled Aggregate and Partial ... - IJERT

The use of recycled concrete aggregate and fly ash in the green concrete reduces the adverse effect of environmental pollution and material scarcity. The use of recycled aggregate will solve the problem of construction and demolition waste disposal. Fly ash, a waste generated by thermal power plants is as such a big environmental concern. The investigation reported in this paper is carried out ...

Similarly, the use of fly ash caused only small reductions in the compressive strength of recycled aggregate concrete. In contrast, the negative effects of recycled aggregates and fly ash were greater in the tensile strength than in the compressive strength. Lastly, the cases containing fly ash exhibited much higher resistance to chloride penetration, even in the cases with recycled aggregates.
