High quality of mortar with marble waste aggregate

Abstract The use of industrial waste has raised great interest regarding its potential of contributing both to the reduction of costs and to sustainable development. In this context, there has been an increasingly high number of studies addressing the use of alternative materials in the construction industry, especially when considering the difficulty in obtaining building materials near urban centers, which results in an increase in the final price due to transportation costs. This research has characterized and evaluated the use of crushed marble waste to replace natural sand in the production of mortar. Many admixtures of mortar were subject to research regarding their physical and mechanical properties. It has been concluded that mortars produced with sand made of crushed marble waste have improved mechanical properties when compared to traditional mortar.摘要 工业固废的资源化利用兼具降低生产成本与推动可持续发展的双重潜力，因此受到广泛关注。在此背景下，建筑行业对替代建材的研究与应用日益增多；尤其在城市周边地区天然建筑材料获取难度加大的情况下，运输成本的增加会进一步推高工程最终造价。本研究针对破碎大理石废料替代天然砂制备砂浆的应用开展了性能表征与效果评价。研究团队针对该砂浆的多种配合比，开展了物理与力学性能的测试分析。最终研究结论表明：相较于传统砂浆，采用破碎大理石废料砂制备的砂浆，其力学性能得到了显著提升。
