| Abstract | ||||
| Recent trends have seen an increased use of industrial by-products, such as blast furnace slag, fly ash, and glass powder, to enhance the mechanical properties of concrete, particularly in applications requiring high abrasion resistance, such as rigid pavements. This paper examines the performance of concrete where glass powder is utilized as a partial replacement for sand. The sand was substituted with glass powder in varying proportions, ranging from 0% to 20% of the cement weight. To enhance the abrasion resistance and durability of concrete, glass powder is being utilized, which also contributes to improved compressive and flexural strengths, ultimately extending the lifespan of rigid pavement structures. Tests conducted included air content, slump, flexural strength, compressive strength, abrasion resistance, absorption, X-Ray Diffraction (XRD), X-Ray fluorescence (XRF) and Scanning electron microscope (SEM). The results show that the optimal strength of concrete is achieved at approximately 15% glass powder when using cement Elarish and around 10% glass powder when using cement Elsewedy. | ||||
