The invention discloses an artificial aggregate and a preparation method and application thereof.The preparation method comprises the following steps that by mass, 85-100 parts of concrete slurry waste, 0-10 parts of urban solid waste incineration bottom ash and 0-5 parts of shell powder are mixed, and a mixture is obtained; carrying out cold bonding granulation on the mixture to obtain an artificial aggregate blank; maintaining the artificial aggregate green body to obtain the artificial aggregate; wherein neither the urban solid waste incineration bottom ash nor the shell powder is 0 part. The concrete slurry waste is used as a main raw material, the urban solid waste incineration bottom ash and the shell powder are added, the prepared artificial light cold bonding aggregate has excellent carbon sequestration capacity and mechanical property, the compressive strength of the artificial aggregate cured for 28 days reaches 1.36 MPa, and CO2 capable of being absorbed by 1000 kg of the artificial aggregate can reach 46.63 kg. The raw materials adopted by the invention belong to wastes, so that the resource utilization of the wastes is realized, and the environmental influence of concrete production is reduced.
本发明公开一种人造骨料及其制备方法与应用，制备方法包括如下步骤：按质量份计，将混凝土泥浆废弃物85‑100份、城市固废焚烧底灰0‑10份、贝壳粉0‑5份进行混合，得到混合料；将混合料进行冷粘结造粒，得到人造骨料坯体；将人造骨料坯体进行养护后，得到人造骨料；其中，城市固废焚烧底灰和贝壳粉均不取0份。本发明以混凝土泥浆废弃物为主要原料，加入城市固废焚烧底灰和贝壳粉，制备得到的人造轻质冷粘合骨料具有优异的固碳能力和力学性能，养护28天的人造骨料抗压强度达到1.36MPa，1000kg人造骨料能吸收的CO2可达46.63kg。本发明采用的原料均属于废物，实现了废物资源化利用，降低了混凝土生产的环境影响。
