Abstract: The increasing demand for sustainable construction materials has prompted research into alternative materials, one of which is glass powder. This study evaluates the effect of adding glass powder on the compressive strength and modulus of elasticity of concrete. An experimental method was conducted with variations in glass powder content of 0%, 1%, 2%, 3%, and 4% by aggregate weight. The concrete was tested to determine its compressive strength and modulus of elasticity, with testing carried out at the Civil Engineering Laboratory. The results showed that the addition of 2% glass powder provided the optimal increase in compressive strength, reaching 20.75 MPa, compared to concrete without glass powder, which had a compressive strength of 17.27 MPa. The addition of 3% and 4% also improved compressive strength, though slightly lower than the 2% addition. Conversely, the 1% glass powder addition reduced the compressive strength to 10.82 MPa. The modulus of elasticity of the concrete increased significantly with the addition of 3% glass powder, reaching 2,924.670 MPa, which is higher than concrete without glass powder (2,353.373 MPa). The most significant increase occurred between 1% and 2% glass powder. However, with 4% glass powder, there was a slight decrease in the modulus of elasticity.
