Abstract (en)
[origin: WO2020221631A1] The method for recycling and recovering concrete sludge comprises a step of processing the concrete sludge which consists in separating the granulates contained in the concrete sludge from the water loaded with laitance contained in the concrete sludge; a step of clarifying and drying which consists in clarifying the water loaded with laitance, which has been separated in the concrete sludge processing step, and drying the laitance contained in the water loaded with laitance; a first step of use which consists in using the separated granulates as raw material for manufacturing concrete; and a second step of use which consists in using at least part of the clarified water produced in the clarification and drying step as raw material for manufacturing concrete.
