Geopolymer concrete mix proportion design method based on dredged sand and artificial soft stone

The invention relates to a geopolymer concrete mix proportion design method based on dredged sand and artificial soft stone. Dredged sand and artificial soft stone are used as aggregates, fly ash and slag powder are used as admixtures, sodium silicate and sodium hydroxide are used for preparing an alkaline activator for activating the fly ash and the slag powder, and the average compressive strength of 28 days and the final slump are used as targets. A certain amount of artificial soft stone, dredged sand, an admixture alkaline activator, a binder, fly ash and slag powder are respectively doped according to a certain ratio to prepare target concrete. The device is made based on dredged sand and artificial soft stone. The dredged sand is a waste for river channel improvement, is wide in source, and can be reasonably utilized to turn waste into wealth, save resources and reduce the pressure to the environment and the damage to cultivated land during stacking; the preparation process is simple and low in cost.
