Application of household garbage incineration bottom ash in concrete
The invention discloses an application of household garbage incineration bottom ash in concrete, and relates to the technical field of concrete preparation, the household garbage incineration bottom ash comprises a household garbage bottom ash mixture and a concrete mixture, the household garbage bottom ash mixture is composed of household garbage bottom ash and fly ash, the concrete mixture is prepared from cement, sand, iron powder, ceramsite, stannous chloride and kaolin, and the household garbage bottom ash is pretreated bottom ash, specifically, the household garbage bottom ash is subjected to sieving and magnetic separation treatment. The bottom ash is subjected to metal screening, coarse powder screening and fine powder screening, so that selection is facilitated according to the preparation requirements of the concrete; according to the present invention, the concrete is added with the fine bottom ash, such that the mechanical property and the durability of the concrete can be improved by using the micro-aggregate filling effect, the micro-crystal nucleus effect and the active effect of the bottom ash, and the shrinkage deformation of the concrete is small after the low powder with the fine particle size is doped into the concrete.
本发明公开了生活垃圾焚烧底灰在混凝土中的应用，涉及混凝土制备技术领域，包括生活垃圾底灰混合物与混凝土混合物，所述生活垃圾底灰混合物由生活垃圾底灰、粉煤灰组成，所述混凝土混合物由水泥、砂子、铁粉、陶粒、氯化亚锡以及高岭土，所述生活垃圾底灰为经过预处理的底灰，具体的为所述生活垃圾底灰进过筛分以及磁选处理。通过对底灰进行一个金属筛选，以及粗粉、细粉的筛选，利于根据混凝土的制备要求进行选择；且在混凝土中添加颗粒较细的底灰，可利用底灰的微集料填充效应以及微晶核效应、活性效应改善混凝土的力学性能，以及耐久性，同时，粒径越细小的低粉掺入混凝土后，混凝土的干缩变形越小。
