Steel slag synergistic furnace bottom slag 3D printing concrete
The invention relates to the technical field of construction and building materials, and mainly relates to steel slag and furnace bottom slag synergistic 3D printing concrete. The invention provides steel slag and hearth slag synergistic 3D printing concrete. The steel slag and hearth slag synergistic 3D printing concrete is prepared from the following components: low-alkalinity quick-hardening sulphoaluminate cement, mineral powder, ground hearth slag powder, steel slag, hearth slag fine aggregate, a water reducing agent, an early strength agent, a retarder, chopped fibers and water. The invention further provides a preparation method of the steel slag and hearth slag synergistic 3D printing concrete. The 3D printing concrete is prepared through cooperation of the steel slag, the mineral powder, the furnace bottom slag and the ground furnace bottom slag powder, high bonding strength among aggregate, cement mortar and aggregate in the prepared concrete can be achieved, good constructability and flowability are achieved, the production cost is reduced, the performance of a product is improved, and the 3D printing concrete is suitable for large-scale production. The method has the social and economic benefits of turning waste into wealth, protecting the environment and saving resources.
本发明涉及建筑建材技术领域，主要是一种钢渣协同炉底渣3D打印混凝土。本发明提供的一种钢渣协同炉底渣3D打印混凝土，包括如下组分：低碱度快硬硫铝酸盐水泥、矿粉、磨细炉底渣粉、钢渣、炉底渣细集料、减水剂、早强剂、缓凝剂、短切纤维、水。本发明还提供了所述钢渣协同炉底渣3D打印混凝土的制备方法。本发明通过利用钢渣、矿粉、炉底渣、磨细炉底渣粉三者协同制备3D打印混凝土，能够使得制备的混凝土中骨料‑水泥胶浆‑骨料间具有较高的粘结强度，且具有良好的可建造性和流动性，不仅降低了生产成本，还使得产品的性能得到提升，具有变废为宝、保护环境、节约资源的社会经济效益。
