Preparation process for preparing concrete from machine-made sand and industrial waste residues
The invention belongs to the technical field of concrete preparation, and particularly relates to a preparation technology for preparing concrete from machine-made sand and industrial waste residues, an adopted preparation device comprises a stirring tank, a conveying pipe is vertically arranged in the stirring tank, and the position, close to the top end, of the conveying pipe is fixedly sleeved with a first fixing ring. The concrete prepared by the invention comprises slag cement, and the slag cement is prepared from the following raw materials: 18 to 23 parts of steel slag, 20 to 32 parts of blast furnace slag, 6 to 14 parts of Portland cement clinker, 1 to 2 parts of gypsum powder, 13 to 14 parts of industrial silicon dioxide, 2 to 4 parts of industrial aluminum oxide, 0.2 to 0.28 part of naphthalene sulfonate, 0.01 to 0.04 part of polycarboxylic acid and 1.2 to 1.8 parts of polypropylene fiber. The mixing effect of powder raw materials such as industrial waste residues and cement balls and other raw materials in concrete can be improved, and the preparation efficiency of the concrete is improved.
本发明属于混凝土制备技术领域，尤其涉及一种机制砂与工业废渣制备混凝土的制备工艺，采用的制备装置包括搅拌罐，所述搅拌罐内竖直设置有输送管，所述输送管靠近顶端的位置固定套接有第一固定环。本发明所制得的混凝土包括矿渣水泥，该矿渣水泥的原料组成包括：钢渣 18‑23 份，高炉矿渣 20‑32 份，硅酸盐水泥熟料 6‑14份，石膏粉 1‑2 份，工业用二氧化硅 13‑14 份，工业用三氧化二铝2‑4 份，萘磺酸盐 0.2‑0.28 份，聚羧酸 0.01‑0.04 份，聚丙烯纤维 1.2‑1.8 份。本发明能够提高工业废渣以及水泥团等粉末原料与混凝土中其他原料的混合效果，提升混凝土的制备效率。
