Special concrete based on waste resource utilization, and preparation process thereof

Abstract

The invention discloses a special concrete based on waste resource utilization, and a preparation process thereof, and relates to the technical field of buildings. The special concrete is prepared from, by weight, 100 to 120 parts of a tailing material, 200 to 300 parts of fly ash, 50 to 80 parts of cement, 5 to 10 parts of a water reducing agent, 500 to 700 parts of stone, 90 to 100 parts of reinforcing fiber and 200 to 350 parts of water. The tailing material containing quartz is ground, so that quartz molecules on the surface of the tailing material tend to be in disordered glass transition, and therefore, the tailing material has certain activity and interacts with a cementing material in cement, so the hardness and wear resistance of the concrete are improved; and meanwhile, a certain proportion of fly ash is doped in the concrete, so the properties of the produced special concrete are improved, the tailing and the fly ash are efficiently recycled, and the preparation cost of the special concrete is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a special concrete based on waste resource utilization and a preparation process thereof. Background technique [0002] While natural mineral resources are becoming increasingly scarce, a large amount of tailings discharged during the development of domestic mineral resources have not been effectively utilized. With the improvement of the development of mineral resources, the mineable grade of ore has decreased correspondingly, and the discharge of tailings has also increased. Increase. The traditional tailings treatment method generally stores the tailings in a harmless manner to prevent the tailings waste from being blown by the wind and washed by the rain and transferred to other places to pollute the environment, but this traditional harmless treatment method is only to a certain extent Controlling the spread of tailings pollution cannot fundamentally solve ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a special concrete based on waste resource utilization and its preparation process. Through the design of the tank structure, mixing components, rotating scraping mechanism, grinding drive mechanism and sealing drive assembly, the existing problems are solved. Tailings and fly ash are produced in a large amount, with many types of tailings and complex components. So far, there is still a lack of efficient, environmentally friendly, economical and applicable, and large-scale comprehensive utilization technologies and products for tailings and fly ash. The existing concrete production The equipment only supports the mixing process of mixed materials, and lacks the material grinding and screening structure, which makes the fineness of the mixed materials lower, which in turn greatly reduces the production quality of concrete, and cannot meet the problems of concrete preparation for different construction needs
