Solid waste is among the World's most critical environmental issues. One of the most significant shares of total solid waste is occupied by electronic waste. One way to reduce waste is to use it as an aggregate in Sustainable Concrete (SC). However, there is little research on using waste electrical cable rubber (WECR) or Waste Electrical Cable plastic (WECP) in concrete, unlike waste tire rubber and plastic in concrete, which have attracted much attention among researchers. Research was conducted by substituting waste electrical cable - plastic sand (WEC-PS) instead of natural sand, and Waste Electrical Cable -Rubber Filler (WEC-RF), as an addition in concrete, accounted for 5%, 10%, 15%, and 20% respectively for both. Researched compressive strength, flexural strength, splitting strength, modulus of elasticity, and unit weight of concrete. Experimental studies revealed that replacing natural sands with WEC-PS increases strength by 18.10%. It seems obvious that replacing natural sands with WEC-PS up to 15% or adding WEC-RF up to 5% increases the mechanical properties of concrete. However, the situation changes when using in large ratios.
