Moreover, RA can be used as an aggregate replacement material which not only reduces disposal quantities but also supports sustainable construction [2], [12], [13]. RAC has more interfacial transition zone (ITZ) between aggregate and mortar than traditional concretes due to the use of RA instead of natural aggregates [14], [15], [16] .

Utilizing Polyethylene Terephthalate PET in Concrete: A Review
In the case of using PET as a replacement material, adding 1–8% would increase split tensile strength by 1–20%. On the other hand, if PET is used as a coarse aggregate replacement, that would negatively affect the split tensile strength. In the case of adding PET polyester to the concrete, this leads to a reduction in split tensile strength.

Recycling of waste glass as aggregate in cement-based materials
Afshinnia's and Rangaraju's [45], research shows using glass powder as a 20% replacement (by weight) for aggregate reduces the 28-day compressive strength by 15% when using traditional aggregate. This can be partially attributed to the fineness of the waste powder being 17 μm, significantly decreasing the water to powder ratio.
