Red mud-based solid waste pervious concrete as well as preparation method and application thereof
The invention relates to the technical field of pervious concrete, in particular to red mud-based solid waste pervious concrete as well as a preparation method and application thereof. The pervious concrete is prepared from the following raw materials in parts by weight: 55-75 parts of red mud, 5-20 parts of blast furnace slag, 0-30 parts of carbide slag, 0-25 parts of alkaline residue, 1-5 partsof a saltpetering inhibitor, 1-9 parts of a cementing agent, 0.5-1 part of a water reducing agent, 0.1-1 part of a reinforcing agent and 30-50 parts of aggregate. The red mud cooperates with various solid wastes such as the slag, the carbide slag and the alkaline residues, so that the prepared red mud-based pervious concrete material has excellent properties such as air permeability, water permeability, light weight, high bearing capacity, high heat dissipation and wear resistance. Besides, the alkaline components (Na and Ca) are fixed by the saltpetering inhibitor in a chemical bonding manner, so that leaching of the alkaline components in the red mud-based pervious concrete can be effectively controlled, and the problem that the red mud-based solid waste pervious concrete is prone to saltpetering and weathering is solved.
本发明涉及透水混凝土技术领域，具体涉及一种赤泥基固废透水混凝土及其制备方法与应用。所述透水混凝土的原料包括以下重量份的组分：赤泥55～75份、高炉矿渣5～20份、电石渣0～30份、碱渣0～25份、泛碱抑制剂1～5份、胶结剂1～9份、减水剂0.5～1份、增强剂0.1～1份、骨料30～50份。本发明通过赤泥协同矿渣、电石渣、碱渣等多种固废，制备的赤泥基透水混凝土材料具有透气、透水、重量轻、高承载力、高散热性和耐磨等优良性能。另外，本发明采用的泛碱抑制剂通过化学键合的方式对碱性组分(Na、Ca)进行固定，可以有效控制赤泥基透水混凝土中碱性组分的浸出，解决了赤泥基固废透水混凝土容易泛碱和风化的问题。
