Abstract
A preparation method of a rubber powder-sediment-fly ash artificial fine aggregate is provided. The rubber powder-sediment-fly ash artificial fine aggregate is prepared by a rolling and compression granulator through layer-by-layer coating of a rubber powder, a canal sediment, and a hydraulic material. The compact arrangement and aggregation are achieved for an artificial aggregate by applying a pressure to improve the compactness of the aggregate. In addition, an aggregate is cured through a multi-stage high-temperature treatment and carbon dioxide air-cooling to further improve the compactness and strength of the aggregate. When the artificial fine aggregate is used as a fine aggregate, solid wastes can be reasonably utilized under the premise of meeting quality standards, which is of great practical significance for protecting the ecological environment and promoting the sustainable development of sand and gravel industry.
