Recycled Concrete as Aggregate for Structural Concrete Production [PDF]
Sustainability, 2010 A comparative analysis of the experimental results of the properties of fresh and hardened concrete with different replacement ratios of natural with recycled coarse aggregate is presented in the paper. Recycled aggregate was made by crushing the waste concrete of laboratory test cubes and precast concrete columns. Three types of concrete mixtures were

Influence of the ITZ Thickness on the Damage Performance of Recycled Concrete
Advances in Materials Science and Engineering, 2021 The interfacial transition zone (ITZ) is a weak region of recycled concrete. To further study the influence of the ITZ on the damage performance of recycled concrete, a formula for calculating the ITZ thickness is derived, and the ITZ thickness is ...

Recyclability of recycled concrete products in cement
5TH INTERNATIONAL CONFERENCE ON TECHNOLOGIES & BUSINESS MODELS FOR C IRCULAR ECONOMY: BOOK OF ABSTRACTS, 2022 This research addresses the recycling possibilities of a concrete product that contains coarse concrete aggregate as recycled material. The use of this finely milled product is proposed as an active addition to cement that already includes by-products in their composition.
