Preparation method of concrete expanding agent
The invention discloses a preparation method of a concrete expanding agent, and relates to the technical field of expanding agents, and the preparation method of the expanding agent comprises the following steps: S100, preparing raw materials; S101, mixing the raw materials; S102, preparing auxiliary materials; and S103, preparing the expanding agent. Modified polypropylene fibers are added into the raw materials of the expanding agent, so that the fracture toughness and the impermeability of concrete can be improved, and the expanding agent has good hydrophilicity, so that the dispersing performance and the adaptability of the expanding agent are good; meanwhile, through cooperation of modified kaolin, silica fume and steel slag, concrete raw materials can be saved, the production cost isreduced, and the strength of concrete is improved; the concrete expanding agent prepared by adopting the method has the advantages of high expansion rate, strong adaptability, good shrinkage compensation effect, high compression strength and high breaking strength, and is simple in preparation process, convenient to operate, relatively low in cost and suitable for large-scale production.
本发明公开了一种混凝土膨胀剂的制备方法，涉及膨胀剂技术领域，所述膨胀剂的具体制备方法包括以下步骤：S100原料准备；S101原料混合；S102辅料制作；S103膨胀剂制作。本发明膨胀剂原料中添加有改性聚丙烯纤维，能够提高混凝土的断裂韧性和抗渗能力，且其具有良好的亲水性，使得其分散性能好，适应性强；同时，通过改性高岭土、硅灰、钢渣的配合，能够节省混凝土原料，降低生产成本，改善混凝土的强度；采用本方法制备的混凝土膨胀剂具有膨胀率高、适应性强、补偿收缩作用好、抗压、抗折强度高的优点，其制备流程简单，操作方便，成本较低，适宜大规模生产。
