The purpose of this research is to recycle combined glass and plastic waste to produce ferrous concrete with improved properties and then use it to cast slabs and investigate its structural properties. A mixture of 10% glass waste as powder was used and 5% and 10% crushed plastic waste as fine aggregate. Twelve one-way slabs have been tested, and compressive and flexural strength. It seems that glass powder has little influence on the flow compared to the influence of plastic. Adding 10% glass powder raised the compressive strength from 25 for reference to 31.2 MPa. However, the compressive strength decreases when waste plastic is substituted for sand in specimens including and without glass powder; however, the strength of glass mixtures remains higher when compared to reference and specimens containing only plastic aggregate. Like compressive strength, the modulus of rupture decreased as the replacement level of plastic aggregate increased. Adding plastic alone helped improve the ductility of concrete but reduced the compressive strength. However, using glass with plastic in the same mixture has significantly improved the properties of concrete in terms of strength and energy absorption represented by increasing the area under the load-deflection curve. Regarding the effect of the type of mesh, it has no clear effect on the crack pattern, it can be compared to each slab of the aggregate reinforced with a square clamp to its counterpart and reinforced with a polygonal mesh, it can be found a similarity between the two patterns. It can be noticed that the number of cracks in slabs, especially those containing plastic aggregate, is higher than the reference and are also spread over a wider area.
