"Recycled aggregates can be obtained from waste materials such as brick mixes, crushed concrete, or ceramics without the additional use of sand or gravel for concrete production," adds Jirí Fiala, Head of Technological Department at ERC-Tech, a European company that provides the Effective Recycling Concrete Technology.

Structural Adequacy of Recycled Coarse

This work presents experimental investigations on structural adequacy of recycled coarse aggregates in production of structural and non-structural concrete. Natural coarse aggregate used was crushed stones with 20mm maximum size. While recycled coarse aggregates used were extracted from concrete box culverts.

Use of recycled aggregates for cement

Recycled Aggregates (RA) from Construction and Demolition Waste (CDW) contain natural aggregates, hardened cement paste but also masonry, plaster, etc. Part of these recycled aggregates are hardly suitable for concrete production due to their water absorption (cement paste porosity, clays) and reactivity (sulphate or alkalis release, etc.).

15-04-2021· 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.

Use of Recycled Concrete Aggregates in

Recycled concrete aggregates (RCA) are used in existing green building composites to promote the environmental preservation of natural coarse aggregates (NCA). Besides, the use of RCA leads to potential solutions to the social and economic problems caused by concrete waste. It is found that insufficient information on the longevity and sustainability of RCA production is a serious issue that

The use of crushed concrete waste as recycled aggregate serves as a solution with outstanding potential for reducing landfill volume. Conversely, recycled concrete, as it is known, is characterised by a large physical and mechanical shortcomings (Li et al. 2008).
