【 摘 要 】

Electrical appliances are becoming an everyday part of our lives. The more we use them, the more we contribute to the emergence of new waste - electronic waste (WEEE). E-waste is a significant source of plastics, metals and others. Electronic waste (cables) as a volume substitute for natural aggregates (5, 10 and 20%) in our experimental work was used. Flexural and compression was observed on prepared samples, beams 100x100x400 mm. The use of electrical waste as a filler has resulted in a slight reduction in the resulting strengths (about 10%), but the properties of the concrete with dispersed reinforcement have been founded. Flexural strengths ranged from 3.5 to 5.1 MPa and compressive strengths were in the range of 15.2 to 28.2 MPa after 28/60 days of curing.
