The influence of curing conditions on the mechanical performance of concrete made with recycled concrete waste [PDF]

Cement and Concrete Composites, 2011
Research on the use of Construction and Demolition Waste (CDW) as recycled aggregate (in particular crushed concrete) for the production of new concrete has by now established the feasibility of this environmentally-friendly use of otherwise harmful ...

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 ...

Improvement mechanism of recycled concrete using C-S-H type accelerator and modifying recycled aggregate by carbonation technology

Acta Polytechnica CTU Proceedings, 2022
In Japan, there is concern that concrete blocks due to demolition will increase with the renewal of concrete structures. Although it has been used for roadbed materials as recycling, in recent years, aggregates are removed from the concrete mass by ...

Cost-benefit analysis of the production of ready-mixed high-performance concrete made with recycled concrete aggregate: A case study in Thailand

Heliyon, 2020
In the current green concrete structures, recycled concrete aggregate is used as recycled concrete waste. In this process, concrete waste is collected and crushed using a recycling procedure in order to produce crushed concrete which is then used in ...

Study for re-ASR behaviour of recycled concrete using ASR generated concrete and considering countermeasure technology

Acta Polytechnica CTU Proceedings, 2022
It is predicted that the concrete volume to be discarded will increase due to the renewal of the concrete structures and the increase in the returned concrete from construction site.
