Construction or demolition will generate a large amount of concrete waste. Concrete waste is large in volume and difficult to degrade. Traditional landfill treatment methods are no longer sufficient for treatment. Therefore, concrete needs to be recycled, such as as aggregate for recycled concrete. Recycled concrete refers to the new concrete made by crushing, cleaning, and grading discarded concrete blocks, mixing them with grading in a certain proportion, partially or completely replacing natural aggregates such as sand and gravel (mainly coarse aggregates), and then adding cement, water, etc.
