Abstract
This work investigates the feasibility of utilizing reactive recycled powder (RP) from construction and demolition (C&D) waste as supplementary cementitious material (SCM) to achieve a ductile strain hardening cementitious composites (SHCC). The recycled mortar powder (RMP) from mortar waste, recycled concrete powder (RCP) from concrete waste and recycled brick powder (RBP) from clay brick waste were first prepared, and the micro-properties and tensile behavior of SHCC containing various types and replacement ratios of RPs were determined. The incorporated RP promotes pozzolanic and filler effects, while the hydration products in cementitious materials decrease with RP incorporation; therefore, the incorporated RP decreases… More >
