Abstract

The invention belongs to the technical field of waste recycling, and particularly relates to a method for manufacturing artificial gravels by utilizing casting fly ash and the artificial gravels. The invention relates to a method for manufacturing artificial gravels by using casting fly ash, which comprises the following steps: (1) uniformly mixing the casting fly ash with cement to obtain a mixture A; (2) adding the mixture A into a stirrer, adding water, and uniformly stirring to obtain a mixture B; (3) putting the mixture B into a mold, pressurizing, and pressing into a sheet; and (4) adding water into the slices for maintenance, crushing the slices into particles, and screening the particles to obtain the artificial gravels. According to the method for recycling the casting fly ash, the casting fly ash is used for manufacturing the artificial gravel, the cylinder compressive strength of the prepared artificial gravel can reach 8 Mpa or above, and the density of the prepared artificial gravel is 1450-1600 kg/m3; therefore, the artificial gravel can replace natural gravel, wherein the utilization value of the casting fly ash is greatly improved, and the cost is reduced. Meanwhile, the problem of shortage of natural gravels is also relieved.

Description

technical field [0001] The invention belongs to the technical field of waste recycling, and in particular relates to a method for manufacturing artificial stones by using foundry dedusting ash and the prepared artificial stones. Background technique [0002] At present, most of the stones used in the construction industry come from mining, but the large-scale mining of mines will seriously affect the normal ecological cycle of the natural environment. In order to prevent environmental damage and avoid resource depletion, mining has gradually been standardized. It is increasingly in short supply, making it difficult to meet market demands. Therefore developing a kind of artificial pebble to substitute natural stone is very important. [0003] At present, the treatment of casting dust ash is still in its infancy in the prior art, and most of the dust ash is still landfilled as solid waste or handed over to brick factories for treatment, with low utilization value and low adde...
