| description | The invention relates to a mineral admixture and application thereof. The mineral admixture comprises oil shale ash and a water reducing agent, wherein in the mineral composition of the oil shale ash, the mass fraction of an amorphous phase is greater than or equal to 70%, and the mass fraction of a quartz phase and a feldspar phase is greater than or equal to 15%; the carbon element content of the oil shale ash is less than or equal to 6%, and the sulfur element content is less than or equal to 3%; and the specific surface area of the oil shale ash is 800m < 3 >/kg to 1500m < 3 >/kg. The mineral composition, the carbon element content and the sulfur element content of the oil shale ash are limited, and meanwhile, the specific surface area of the oil shale ash is limited, so that the oil shale ash as a mineral admixture can meet the performance provided by a composite mineral admixture prepared from various materials such as mineral powder, coal ash and silicon powder. Furthermore, only the oil shale ash disc |
