Active concrete and preparation method of active concrete prefabricated part thereof

The embodiment of the invention discloses active concrete and a preparation method of an active concrete prefabricated component thereof, and the preparation method comprises the following steps: putting a composite high-performance admixture into a stirrer, and stirring for 2-3 minutes until the mixture is uniformly stirred; adding river sand into the stirred composite high-performance admixture, and stirring for 2-3 minutes until the composite high-performance admixture completely wraps the surface of the river sand; the stone is added and stirred for 1-2 min until the composite high-performance admixture and the river sand completely wrap the surface of the stone, and a mixture is formed; steel fibers, an anti-settling agent and a water reducing agent are added into the mixture, mixing and stirring are conducted for 2 min, and the matching compactness is improved by designing reasonable sand and composite high-performance admixture external gradation; special springs are used for replacing fibers, and mean
