Self-flowing heat-resistant concrete utilizing waste electric porcelain
The invention discloses self-flowing heat-resistant concrete utilizing waste electric porcelain. The self-flowing heat-resistant concrete contains the following components in percentage by weight: 65-70% of waste electric porcelain aggregate; 10%-15% of waste electric porcelain fine powder; 3-7% of silica powder; 12-20% of a binding agent; and 0.1-0.5 wt% of a water reducing agent is added on thebasis. The invention provides the self-flowing heat-resistant concrete for the high-temperature parts of the blast furnace foundation and the casting house platform; meanwhile, the waste electroceramics can be recycled, the content of the waste electroceramics in the obtained self-flowing heat-resistant concrete is 70wt% or above, and the use temperature can reach 1,300 DEG C or above. The high strength and good sintering stability of the waste high-voltage electric porcelain are fully utilized, secondary utilization of solid waste resources is achieved, and the cost is reduced. By adopting the zirconium-removed silica powder, impurities are few, the fluidity is good, the water consumption is greatly reduced, the material can be pumped for construction, and the construction efficiency is greatly improved.
本发明公开了一种利用废旧电瓷的自流耐热混凝土，其组成按重量百分数计如下：废旧电瓷骨料65～70％；废旧电瓷细粉10～15％；硅微粉3～7％；结合剂12～20％；在以上基础上外加减水剂0.1～0.5wt％。本发明提供一种用于高炉基础和出铁场平台高温部位的自流耐热混凝土，同时能够对废旧电瓷资源化利用，所得自流耐热混凝土中废旧电瓷含量在70wt％以上，使用温度可以达到1300℃以上。充分利用了废弃高压电瓷的强度高，烧结稳定性好，做到了固废资源二次利用，降低了成本。通过采用脱锆硅微粉杂质少，流动性好，大幅度降低用水量，材料能泵送施工，大幅度提高施工效率。
