Marble dust (MD) and granite dust (GD) are generated during the processing (cutting and grinding) of marble and granite, respectively. The dust generated by the mentioned stones is non-biodegradable, which creates various environmental and health hazards. In view of this, incorporation of MD/GD as a replacement for cement to prepare sustainable cementitious composites (such as concrete and mortar) has gained substantial popularity. This article critically discusses the effect of MD/GD on engineering properties of cementitious materials. In addition, to discuss the sustainable development and challenges related to the preparation of MD/GD-modified cementitious materials, 100 researchers worldwide were asked about key sustainability benefits and critical challenges to adding MD/GD in cementitious composites as cement replacement. According to the published literature and responses of researchers, MD/GD are suitable candidates to replace a considerable amount of cement in preparing cementitious composites since they can reduce environmental pollution and costs without causing detrimental effects to engineering properties of prepared cementitious composites. Finally, based on participants’ responses and the published works, a framework for successful development of cementitious materials with MD/GD is presented, which (if applied) can promote commercial use of MD/GD like slag.

在大理石和花岗岩的加工（切割和研磨）过程中分别产生大理石粉尘（MD）和花岗岩粉尘（GD）。由上述宝石产生的灰尘是不可生物降解的，这会造成各种环境和健康危害。鉴于此，掺入MD / GD作为水泥的替代品以制备可持续的水泥复合材料（例如混凝土和砂浆）已受到广泛欢迎。本文批判性地讨论了MD / GD对胶凝材料工程特性的影响。此外，为了讨论与MD / GD改性水泥材料制备有关的可持续发展和挑战，全球100名研究人员被问及在水泥复合材料中添加MD / GD的主要可持续性优势和关键挑战。水泥更换。根据已发表的文献和研究人员的反馈，MD / GD是制备水泥复合材料时替代大量水泥的合适候选材料，因为它们可以减少环境污染和成本，而不会对所制备的水泥复合材料的工程性能产生不利影响。最后，根据参与者的反馈和已发表的作品，提出了成功开发含MD / GD的胶凝材料的框架，该框架（如果应用）可以促进MD / GD等矿渣的商业化使用。
