Shield muck biochar-based baking-free brick and preparation method thereof
The invention provides a shield muck biochar-based baking-free brick and a preparation method thereof. The shield muck biochar-based baking-free brick is prepared by pressing shield muck particles, biochar particles, concrete recycled micro-powder, an exciting agent and fibers as raw materials, wherein the mass ratio of each raw material is as follows: 20-30% of the concrete recycled micro powder, 40-70% of the shield residue soil particles, 1-3% of the fibers, 10-20% of the charcoal particles and 2-5% of the exciting agent; the preparation method comprises the following steps: preparation of concrete recycled micro powder, preparation of shield residue soil particles, preparation of biochar particles, preparation of an exciting agent, preparation of fibers, preliminary stirring and mixing of required raw materials, wheel rolling, building block forming and maintenance. The baking-free brick has the advantages of low preparation cost, good product quality and the like, and responds to the national development concepts of kinetic energy conversion, greenness and low carbon.
本发明提供了一种盾构渣土生物炭基免烧砖及其制备方法，由盾构渣土颗粒、生物碳颗粒、混凝土再生微粉、激发剂、纤维为原料压制而成；其中，各原料的质量配比为混凝土再生微粉20‑30％、盾构渣土颗粒40‑70％、纤维1‑3％、生物炭颗粒10‑20％、激发剂2‑5％；制备方法包括：混凝土再生微粉制备、盾构渣土颗粒制备、生物碳颗粒制备、激发剂准备、纤维准备，所需原料初步搅拌混合、轮碾、砌块成型、养护。该免烧砖具备制备成本低、产品质量好等优点，响应国家动能转化、绿色低碳的发展理念。
