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

A large amount of research has been conducted on recycled aggregate concrete (RAC) due to its social, environmental, and economic significance. However, the in situ application of RAC has so far been mainly limited to nonstructural purposes, as the performance of RAC, in both the short and long term, is inferior to its normal concrete counterpart.

2017-8-15  From Fig. 16, it can be observed that the compressive strength of recycled brick aggregate concrete columns is slightly larger than that of brick aggregate concrete columns while an opposite trend was found for stone aggregates. Moreover, it is observed that the FRP wrapping induced an increase of the strength with the larger values obtained ...

2013-3-26  The recycled aggregate replacement ratio (γ) was chosen to be 25 or 50 %. It was found that the mechanical behaviour of the RACFST specimens is similar to that of concrete filled steel tubular (CFST) specimens with ordinary concrete, but the modulus and strength of the former are slightly lower than those of the latter.

Based on the database, the effects of FRP type (i.e., GFRP and CFRP) and the replacement ratio of recycled coarse aggregate were investigated. The results indicated that the stress⁻stain behavior of FRP-confined RAC depended heavily on the unconfined concrete strength and the FRP confining pressure instead of the replacement ratio.
