Behaviour of confined recycled aggregate concrete under ...

2020-11-1  Chen et al. studied the behaviour of CFRP confined recycled aggregate concrete under compression and state that although the compressive strength decreases with the use of recycled aggregates, however, the effectiveness of confinement isn't significantly affected by the replacement ratio.

Behavior of FRP-Confined Recycled Brick Aggregate

Brick waste is the second-largest source of China's construction and demolition waste. Reprocessing brick waste into recycled brick aggregate (RBA) to fabricate new concrete [i.e., recycled brick aggregate concrete (RBAC)] has proved to be an effective solution.

Stress-Strain Behavior of FRP-Confined Recycled

The test results show that specimens with a replacement ratio of 20% behave similarly to that of normal concrete, but specimens with a replacement ratio of 100% exhibit a lower strength and a different stress-strain response. The applicability of two existing stress-strain models for FRP-confined normal concrete to FRP-confined RAC is also ...

The Simple Mix Design Method and Confined Behavior ...

2021-6-24  For the environment protection and sustainable development in building construction, waste concrete can be processed into recycled aggregate to mix the recycled aggregate concrete (RAC). However, the existing mix design methods of RAC were complex, and the mechanical properties of RAC were more weakened than ordinary concrete. This paper presents a simple
