Concrete. Concrete recycling begins with the blasting, breaking and and / or removal of concrete. This material can be hauled away to a recycling facility or more economically, be crushed on site with a portable or mobile crusher. For concrete recycling, impact crusher or jaw crushers are often utilized for crushing the demolished concrete.

Recycled aggregate concrete (RAC) is a promising solution to address the challenges raised by concrete production. However, the current lack of pertinent design rules has led to a hesitance to accept structural members made with RAC. It would entail even more difficulties when facing application scenarios where brittle failure is possible (e.g., beam in shear). In this paper, existing major

However, using a recycled aggregate of more than 65% can impact the mix’s durability significantly, reducing its physical properties tenfold. The optimum amount blended in with the concrete should be 35%. Some experiments have shown that the recycled aggregate is durable, no doubt, but not as sturdy as natural coarse aggregate.
