The demand for materials with improved properties and less negative impact on the environment is growing. Artificial stones are examples of these materials produced with up to 90% of particulate material joined by a binder. This article evaluates the physical and mechanical properties of two artificial stones produced with processing steel residue (blast furnace dust waste) and quartz powder. Two binders were used: pure epoxy resin, denoted as ASPB100, or a mixture of 70 wt% epoxy resin with 30 wt% cashew nut shell oil, denoted as ASPB7030. The process took place under vibration, compression (3 MPa/20 min and 90 °C) and vacuum (80 Pa). ASPB100 showed water absorption of 0.07%, while for ASPB7030, it was 0.54%. They were classified as having high mechanical strength associated with bending stress values equal to 32 and 25 MPa, respectively. Stain resistance indicated that both artificial stones had their stains removed with the tested cleaning agents. In this way, the novel artificial stones produced are sustainable alternatives for the application of blast furnace waste and cashew nut shell oil, reducing their negative impacts on the environment.
对性能更优且对环境负面影响更小的材料的需求日益增长。人造石材就是这类材料的实例，它们由高达90%的颗粒材料与一种粘结剂结合而成。本文评估了两种用人造石材的物理和力学性能，这两种人造石材是用加工后的钢渣（高炉粉尘废料）和石英粉制成的。使用了两种粘结剂：纯环氧树脂，记为ASPB100，或70 wt%环氧树脂与30 wt%腰果壳油的混合物，记为ASPB7030。该过程在振动、压缩（3 MPa/20分钟和90°C）和真空（80 Pa）条件下进行。ASPB100的吸水率为0.07%，而ASPB7030的吸水率为0.54%。它们被归类为具有高机械强度，其弯曲应力值分别等于32和25 MPa。耐污性表明，两种人造石材上的污渍都能用测试的清洁剂去除。通过这种方式，所生产的新型人造石材是高炉废料和腰果壳油应用的可持续替代品，减少了它们对环境的负面影响。
