摘要
随着建筑业的发展,3D 打印技术有望成为未来建筑业的主流方法。通过实施有效的法规,可以将废弃资源重新用作 3D 打印的原材料。本研究探讨了用固体废弃物粉末替代水泥的问题,调查了影响水泥基材料 3D 打印性能的各种因素。研究发现,水-粘合剂比例、粉煤灰含量和钢渣含量对凝固时间有持续影响,其中粉煤灰的影响更大。随着用水量的增加,挤压时间缩短,而粉煤灰和钢渣粉的含量越高,挤压时间越长。虽然添加粉煤灰和钢渣粉可以降低变形率,但可能会影响挤压性。堆叠性方面的变形率与施工性方面的变形率一致。粉煤灰对 1 天抗压强度的影响很大,其次是钢渣粉,而用水量的影响最小。汞侵入孔隙模拟法显示,钢渣粉和粉煤灰对孔隙的影响相似。当含量为 5%时,凝胶孔隙会增加,但替代率越高,有害孔隙的比例越大。在适当的范围内,固体废料粉末可有效地用于建筑施工的三维打印。
The effect of waste powder on the 3D printing performance of cement-based materials
With advancements in the construction industry, 3D printing technology is poised to emerge as the predominant method of construction in the future. By implementing effective regulations, waste resources can be repurposed as raw materials for 3D printing. This study examines the substitution of solid waste powder for cement, investigating various factors impacting the 3D printing performance of cement-based materials. It was observed that the water-binder ratio, fly ash content, and steel slag content consistently influenced the setting time, with fly ash exerting a greater impact. As water consumption increases, extrusion time decreases, while higher levels of fly ash and steel slag powder lead to longer extrusion times. Although the addition of fly ash and steel slag powder can reduce deformation rates, it may compromise extrudability. The deformation rate in terms of stackability aligns with that of buildability. Fly ash significantly affects the 1-day compressive strength, followed by steel slag powder, with water consumption having the least impact. Mercury intrusion porosimetry reveals similar effects of steel slag powder and fly ash on pores. At a content of 5%, gel pores increase, but higher substitution rates result in a greater proportion of harmful pores. Within appropriate ranges, solid waste powder can be effectively utilized in 3D printing for building construction.
