Investigation of 30% recycled coarse aggregate content in sustainable concrete mixes

The improvement of sustainable concrete, by applying recycled coarse aggregates has an important role to ensure the minimization of damages towards environment. The amount of construction waste increases annually. Also modern technology is given a chance to improve recycling usage in sustainable concrete industry. In modern technology world, recycling plays a vital role to protect the natural resources in our planet. This research carries out a thorough investigation of fresh & hardened RCA concrete, the thermal performance (thermal properties & thermal dynamic properties) with 30% recycled coarse aggregate content. It provides a clearer understanding on how it can be applied to improve the usage of 30% RCA content in concrete for sustainable development.
