Regenerated functional aggregate based on engineering spoil and preparation method thereof
The invention provides a recycled functional aggregate based on engineering spoil. The recycled functional aggregate comprises the following components in parts by mass: 240-320 parts of engineering spoil micro powder, 20-40 parts of an alkaline activator, 100-120 parts of cement, 120-180 parts of mineral ultrafine powder, 2-4 parts of water glass and 80-100 parts of water, wherein the mineral ultrafine powder is prepared from fly ash, slag, gypsum and zeolite powder. The water absorption rate, the crushing index and the void ratio of the recycled functional aggregate all meet the standard of recycled coarse aggregate.
本发明提供了基于工程弃土的再生功能骨料，所述再生功能骨料各组分及质量配比为：工程弃土微粉240～320份，碱性激发剂20～40份，水泥100～120份，矿物质超细粉120～180份，水玻璃2～4份，水80～100份；其中矿物质超细粉为粉煤灰、矿渣、石膏和沸石粉制得。该再生功能骨料的吸水率、压碎指标和空隙率均符合再生粗骨料的标准。
