Utilization of ceramic tile demolition waste as supplementary cementitious material: An early-age investigation

Construction and demolition (C&D) activities generate large amounts of waste, such as ceramic tile demolition waste (CTDW). However, the recycling ratio of C&D waste is generally of 3–10%. In this work, pastes with 0–30 wt% replacement of Portland cement by CTDW and limestone (reference filler) were produced. The particle packing, fresh-state properties (mini slump and rheometry), cement hydration (isothermal calorimetry and in situ X-ray...
