Abstract:
Recycled Aggregate Concrete (RAC) has emerged as an environment-friendly alternative to
normal concrete, recycling concrete and using it as aggregate. Large-scale application of RAC
is possible by incorporating a suitable amount of fibers. Aluminum wires are recyclable and
exhibit tendencies to increase the strength of concrete. In this study, normal aggregate concrete
(NAC) and recycled aggregate concrete (RAC) were both incorporated with waste aluminum.
Results from fresh properties and mechanical testing showed that waste aluminum wires
enhance strength by replacement. Lifecycle assessments showed that waste aluminum wire
incorporated in recycled aggregate concrete (WAWIRAC) reduced greenhouse gas emissions
by 16%. This means that WAWIRAC can be an eco-friendly alternative to NAC.
