Recycling Demolished Concrete for Construction Materials
The recycling of demolished concrete is examined by inducing calcium carbonate cementation between the aggregates. Mechanical responses are evaluated through both laboratory tests and numerical simulations, aligned with the certification scheme set by the Government of Abu Dhabi.
