Abstract: A printable cementitious materials named ultra-high performance engineered cementitious composites (UHP-ECC) incorporating recycled fine-powders (RFP) was developed and its mechanical properties were determined in present research. The recycled fine-powders (RFP) was produced during recycling mixed construction and demolition (C&D) materials. Different levels of RFP content 12.5%, 25% and 50% by volume were set. The compressive and tensile properties of UHP-ECC were obtained at 3 day, 7 days and 28 days, respectively, to monitor the mechanical properties in the normal curing age. The compressive and tensile strength increased slightly as the RFP content up to 25% and decreased with the increasing RFP content.
