<p>This study investigates the impact of waste additives on the behaviour of high-performance concrete and its environmental implications, with a specific focus on resource conservation. The research objectives were realised through the preparation of high-performance concrete specimens incorporating industrial waste materials and marble powder as partial replacements for cement and fine aggregates, respectively. Silica fume and ground blast furnace slag were introduced as substitutes for 8% of the cement’s weight. Powdered marble was volumetrically substituted at levels of 5%, 10%, and 15% of the fine aggregates. The physical and mechanical properties of both fresh and cured concrete specimens were evaluated at different ages, encompassing parameters such as density, compressive strength, impulse velocity, water absorption, and durability. The findings demonstrated that high-performance concrete formulated with silica fume and ground blast furnace slag exhibited superior properties compared to compositions relying exclusively on Portland cement. Furthermore, the inclusion of marble powder as an alternative building material constituent in high-performance concrete resulted in increased efficiency and improved resistance against chemical acid attacks. Significantly, this approach contributes to reduce aggregate demands, environmental preservation, and the production of environmentally sustainable concrete.</p>
