The environmental troubles that are related to cement manufacturing makes the new studies moving forward to using materials have less environmental impact, thus, in this paper we utilized different type of recycled glass such as (neon glass, brown glass, and green glass) that has high percentage of silicon dioxide (SiO₂) with different concentrations. Utilization these landfall materials can be considered as keeping on resources. Different waste glasses used as a partial replacement of cement with different concentrations 11%, 13%, and 15% of cement weight for each type, and study the effect of it on the mechanical properties of concrete. After mixing, casting, and curing in water at (20±2)°C for (7, 14, and 28) days, the mechanical properties showed that the compressive strength and flexural show highest results at 13% from cement weight of neon glass, whereas splitting tensile strength appeared the highest value at the same percentage but from green glass.
