CONSTRUCTION AND DEMOLITION WASTE FINE AGGREGATE FOR SUSTAINABLE 3D PRINTABLE CONCRETE: RHEOLOGICAL AND MECHANICAL PERFORMANCE
This study investigates the feasibility of incorporating locally sourced construction and demolition waste (CDW) as fine aggregate replacements in 3D concrete printing (3DCP) mixes. Three mortar mixes were developed: a 100% natural sand reference mix, and two recycled mixes replacing natural sand with processed CDW at...
