Baking-free brick and preparation method thereof
The invention provides a baking-free brick and a preparation method thereof. The baking-free brick is prepared by pressing subway muck, regenerated micro powder, cement, a hardening agent and small blocks of construction waste as raw materials. Wherein the mass ratio of each raw material is as follows: 6%-10% of cement, a hardening agent accounting for 2%-3% of the mass of the cement, 20%-25% of regenerated micro powder and the balance of a small amount of small blocks of construction waste and subway muck; the small blocks of construction waste are one or more of construction waste bricks, construction waste tiles and construction waste concrete blocks; the metro muck comprises metro excavation earth surface clay and a large amount of muck generated by excavation of a shield tunneling machine. The preparation method comprises the following steps: preparation of regenerated micro powder, multi-roll raw material preparation of muck, addition of an additive, 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 the national development concepts of kinetic energy conversion, green and low carbon are responded.
本发明提供一种免烧砖及制备方法，由地铁渣土、再生微粉、水泥、硬化剂、小块建筑垃圾为原料压制而成；其中，各原料的质量配比为：6％‑10％的水泥、所述水泥质量的2～3%的硬化剂、20～25%的再生微粉，其余为少量小块建筑垃圾和地铁渣土；小块建筑垃圾为建筑废砖、建筑废瓦、建筑废混凝土块的一种或数种；地铁渣土包括地铁挖掘地表黏土和盾构机开挖产生的大量渣土。制备方法包括：再生微粉的制备、渣土多辊原料准备、外加剂添加、所需原料初步搅拌混合、轮碾、砌块成型、养护。该免烧砖具有制备成本低、产品质量好等优点。响应国家动能转换，绿色低碳的发展理念。
