Preparation method of concrete prefabricated part
The invention relates to a preparation method of a concrete prefabricated part. The preparation method comprises the following steps: A, a mold is assembled, and the mold is inspected after mold surface treatment; B, a reinforcement cage and various embedded parts are installed on the mold; C, 10-20 parts of cement, 5-10 parts of modified slag powder, 30-40 parts of aggregate, 0.2-0.5 part of early strength additive and 5-10 parts of water are added into stirring equipment, and uniformly stirred and mixed to obtain slag powder concrete; D, the slag powder concrete is poured into the mold to prepare a prefabricated part primary product; and E, surface treatment is performed on the prefabricated part primary product to obtain a prefabricated part finished product. According to the preparation method of the concrete prefabricated part, modified slag powder is adopted to replace about 35% of the total amount of cementing materials (cement) in a traditional prefabricated part concrete formula, so that carbon emission can be greatly reduced; and the slag powder concrete in raw materials is mainly prepared from industrial waste, so that economic benefits are good, and environmental pollution can be reduced.
本发明涉及一种混凝土预制件的制备方法，包括以下步骤：A、拼装模具，模具表面处理后检查；B、将钢筋笼、各种预埋件安装在模具上；C、将水泥10‑20份、改性矿渣粉5‑10份、骨料30‑40份、早强添加剂0.2‑0.5份、水5‑10份加至搅拌设备中，搅拌混合均匀得到矿渣粉混凝土；D、将矿渣粉混凝土倒入模具中制成预制件初产品；E、将预制件初产品进行表面处理，得到预制件成品。本发明的一种混凝土预制件的制备方法，采用改性矿渣粉能取代传统预制构件混凝土配方中胶凝材料(水泥)总量的35％左右，能大大减低碳排放，且原材料中矿渣粉混凝土主要原材料系工业废料，经济效益良好，还可减轻环境污染。
