Therefore, a large number of needle-like and flake-like particles are likely to be produced during the crushing process of fired bricks. Sintered brick aggregates with a large number of needle-like and flake-like particles are used as recycled aggregates to configure concrete. The basic mechanical properties such as compression resistance and splitting of recycled brick aggregate concrete are poor, which restricts the use of recycled brick aggregate concrete. application. If the fired brick aggregate with a large number of needle-shaped and flake-like particles is subjected to secondary processing, the production cost will be increased, which is not conducive to the resource utilization of fired bricks.
