Artificial aggregate as well as preparation method and application thereof
The invention provides an artificial aggregate as well as a preparation method and application thereof, and relates to the technical field of concrete. The artificial aggregate provided by the invention is prepared from the following raw materials in percentage by mass: 10 to 15 percent of concrete residue powder, 10 to 15 percent of cement, 40 to 45 percent of concrete residue fine sand, 5 to 10 percent of adhesive, 5 to 10 percent of exciting agent and 20 to 25 percent of water. Fine sand in concrete residues is used as a main skeleton structure of the aggregate, so that waste is directly changed into a main component of a product, consumption of the concrete waste is promoted, and waste of resources is reduced; compared with aggregate prepared from pure concrete waste residues, the compressive strength of the artificial aggregate provided by the invention can be remarkably enhanced; meanwhile, an exciting agent is added into the concrete residue powder, so that the activity of the concrete residue powder can be excited, and the compressive strength of the artificial aggregate is further improved.
本发明属于提供了一种人造骨料及其制备方法和应用，涉及混凝土技术领域。本发明提供的人造骨料，按质量分数计，包括以下制备原料：混凝土残渣粉料10～15％、水泥10～15％、混凝土残渣细砂40～45％、粘合剂5～10％、激发剂5～10％和水20～25％。本发明使用混凝土残渣中的细砂作为骨料的主要骨架结构，使废弃物直接变为产品主体成分，促进混凝土废料的消纳，减少了资源的浪费；并且本发明提供的人造骨料与纯混凝土废渣所制备的骨料相比，抗压强度能够得到显著增强；同时本发明在混凝土残渣粉料中加入激发剂，可激发混凝土残渣粉料的活性，进一步提高增强人造骨料的抗压强度。
