A review: Properties of eco-friendly ultra-high-performance concrete incorporated with waste glass as a partial replacement for cement

Abstract

Abstract Researchers have shown that recycled materials can be used to substitute some of the mixture components in Ultra-High-Performance Concrete (UHPC) to result in more sustainable building material. One common material that can be recycled to be used in concrete applications is waste glass (WG). This paper presents a literature review on the effects on the fresh and hard mechanical properties of UHPC by recycled waste glass (WG). With the addition of recycled glass, the new material “Ultra-High-Performance Glass Concrete” (UHPGC) becomes extremely workable and possesses rheological characteristics improving fresh concrete behavior due to the low water absorption, smooth surface, and optimized package density of the material. The use of GP (Glass Powder) as a partial cement substitute in UHPGC gives good mechanical characteristics as compressive strength, tensile strength, and bending strength. In addition, the glass powder reduces the penetrability of chloride-ion in concrete and reduces the possibility of chloride-induced steel corrosion. The glass powder’s provide pozzolanic activity. In addition, UHPGC can be designed with a reduced amount of cement as the cement industry is one of the sources emitting CO2.
