1.Introduction. Interest in using recycled concrete aggregates (RCA) from demolished old concrete structures in new construction is growing fast recently .Such interest derives from two problems associated with sustainability, i.e. lack of land for disposing demolished concrete debris and depletion of quality primary natural aggregates for concrete production.

Performance of Recycled Concrete Aggregates: A New Study. Posted on April 15, 2021. It is a basic axiom of environmental stewardship. When possible, use old stuff to make new stuff. The same is true with concrete aggregates. Mixes are more sustainable when recycled concrete aggregate (RCA) replaces natural aggregates, at least to a degree.

Recycled Concrete. Definition: hardened concrete that has been processed for reuse, usually as aggregate.- ACI Concrete Terminology. The reason for recycling is the reduction of waste in order to protect nature against pollution, the increasing shortage of suitable dumping grounds, and to save energy and natural resources.

Milestone in Concrete Recycling. With the new process, old concrete can be completely recycled and saved from landfill. So far, attempts to recycle old concrete have led to rather low recycling rates, and only 30% of primary material can be substituted by these recycled materials in structural concrete.

Recycling concrete aggregates in new concrete, as its scientific effort is aimed at material reuse to help creating more value to an otherwise end-of-life product and enhancing resource efficiency: reuse of concrete aggregatres. So far the innovative full-scale projects in Denmark have only used the coarse fraction 4-25mm. However, when crushing concrete 40-60% is in the 0-4mm fraction.

Uses of Recycled Aggregate: ??? Building the base of a road. The underlying layer forms a structural foundation for paving. ??? Ready mix concrete. This is a mix of water, sand and cement. It can substitute for the brand-new aggregate. This includes uses for walkways, residential streets and concrete paving. ??? Stabilizing the soil.

Crushed concrete can then be reused as an aggregate in new concrete or in any structural layer. This reuse of concrete reduces the need for mining other aggregates such as gravel and relying on the transportation of aggregates. When used in new concrete, the recycled crushed concrete aggregate is usually mixed with a aggregate. But more

Recycled aggregate is waste material from demolished buildings or bridges, for example. When demolishing such structures, the waste needs to be sorted into wood, glass, etc. and concrete. This is called selective demolition, as the structure isn???t knocked down as a whole, but the materials are taken down selectively.
