Development and Application of a High-Volume Recycled Powder Solidifying Material for Waterworks Sludge

Recycled powder (RP) is produced as a by-product during the process of recycling construction and demolition (C&D) wastes, presenting a low additional value. Using RP-based solidifying material can not only improve its utilization efficiency, but also reduce the cost of commercial solidifying materials. To date, this is the best solidifying material utilized to dispose the original waterworks sludge (OWS) with high moisture contents (60%), and...
