Preparation method of limestone-added misfire concrete
The invention discloses a preparation method of limestone-added misfire concrete, and relates to the technical field of concrete production, the limestone-added misfire concrete is prepared by adding limestone machine-made sand into a concrete material, and the concrete used in the preparation of the misfire concrete is ordinary Portland cement. The misfire concrete is mainly prepared by uniformly stirring and mixing a mixed base material, conductive powder, a wear-resistant agent, a mineral admixture and water, and has the advantages that the limestone machine-made sand is added into the mixed base material, so that the interfacial viscosity between cement and coarse aggregate in the mixed base material is improved, and the tensile strength of the mixed base material is enhanced; and the machine-made sand has the advantages of controllable raw materials, controllable production equipment and process, stable performance and the like, and the magnesium aluminate spinel refractory material is added into the mixed base material, so that the mixed base material has good erosion and corrosion resistance, good thermal stability and high temperature resistance, and the service life of the misfire concrete is prolonged.
本发明公开了一种添加石灰岩不发火混凝土的制备方法，本发明涉及混凝土生产技术领域，所述添加石灰岩不发火混凝土是将石灰岩机制砂添加至混凝土材料中，不发火混凝土的制备所使用的混凝土为普通硅酸盐水泥，不发火混凝土主要由混合底料、导电粉、耐磨剂、矿物外加剂和水均匀搅拌混合制成，本发明的优点在于：通过在混合底料中添加石灰岩机制砂，使得混合底料内水泥和粗骨料之间的界面粘性提升，增强其抗拉强度，且机制砂具有原料可控、生产设备和工艺可控、性能稳定等优势，通过在混合底料中添加镁铝尖晶石耐火材料，使混合底料具有良好的抗侵蚀、腐蚀能力，热稳定性好，且耐高温，增加了不发火混凝土的使用寿命。
