Concrete slurry waste, CSW is a unique unhardened construction waste which is rich in silicate minerals generated from concrete ready-mixing plant. However, its recycling has always been greatly restricted owing to its complex composition, high water to solid ratio, hazardous and corrosion. The large-scale recycling methods of CSW are comprehensively reported and commented in this paper, including recycling as aggregates, fillers, cementitious materials (wet grinding technology), additions in concrete and raw materials for cement clinker production; preparation of new type of concrete products and lightweight aggregates by carbonation and cold bonded pelletizing technique; the development in “one or two” part alkali-activated materials (AAMs). The promising research directions of CSW in the future are pointed out as follows: 1. Pre-treatment regeneration technology and active excitation technology with low energy consumption; 2. Carbonation technology; 3. Long term leaching behavior of heavy metals and durability.
