Herein an innovative process to develop a potential vitreous material with cementing properties is proposed. This process paves a production path through melting industrial waste and subsequently cooling the casting in water. The idea erases the need to reduce the environmental impact of the cement industry in terms of natural resources consumption as well as the re-utilization of abandoned wastes from other industries. The recycled industrial wastes were selected according to the amount of waste produced in the industrial field and its suitable chemical composition, such as construction and demolition waste and/or shells from shellfish. As a main result, the mechanical properties showed by our novel material were worse than those reported by blast furnace slag (25⁻28 MPa for two different proportions) for seven days and better (43⁻52 MPa for two different proportions) for 28 days. The rest of the properties evaluated were in agreement with the standards' requirements. Hence, this novel process would help to minimize the environmental impact of these wastes at the same time that their use in the cement industry would reduce the consumption of raw materials.
本文提出了一种创新工艺，用于开发具有胶凝性能的潜在玻璃质材料。该工艺通过熔化工业废料并随后在水中冷却铸件，开辟了一条生产路径。这个想法消除了在自然资源消耗以及其他行业废弃废料再利用方面减少水泥行业环境影响的需求。根据工业领域产生的废料量及其合适的化学成分，选择了回收的工业废料，如建筑和拆除废料以及/或贝类外壳。主要结果是，我们的新型材料在七天时显示的机械性能比高炉矿渣报告的性能（两种不同比例下为25⁻28兆帕）差，而在28天时更好（两种不同比例下为43⁻52兆帕）。评估的其他性能符合标准要求。因此，这种新工艺将有助于最大限度地减少这些废料的环境影响，同时它们在水泥行业的使用将减少原材料的消耗。
