Sustainable development is the development that meets the needs of the present without compromise the availability for
future generations to meet their own needs. Sustainability goals concentrate on the global challenges, including poverty,
inequality, environmental degradation and climate change. Sustainable Construction is the utilization of materials and
products in buildings and construction that will require less use of natural resources and boost the reusability of such
materials and products for the same or similar purpose, thus reducing waste as well. In this research paper, experimental
investigation were carried out to study the strength and durability properties of standard grade recycled aggregate concrete
(RAC), namely M40 with constantly replacing 30% cement by fly ash throughout each sample, keeping all the materials
quality and composition same and only replacing the different percentage of natural aggregate (NA) by recycled aggregate
(RA) to study the properties of RAC. Concrete prepared by natural aggregate concrete (NAC), recycled aggregate concrete
made with 25% replacement of NA by RA (R25),50% replacement of NA by RA (R50), 75% replacement of NA by RA
(R75) & 100% replacement of NA by RA (R100) were tested. The present work results show that the replacement of RA by
NA up to 100 percent does not affect the strength and durability of concrete significantly.
