The present application relates to the technical field of building material recycling, and more particularly to a red mud-based high-performance concrete curb and a preparation method thereof. The curb is prepared from a red mud-based cementitious material, sand, stone, water, a color agent and an additive through a certain preparation method, realizes high-value resource utilization of solid waste such as red mud, improves the performance of the red mud-based concrete curb, is green and environmentally friendly, has a simple preparation process, low cost, high economic benefits, and is suitable for popularization and application.

The invention provides a method for producing a flow-state backfill material by using undisturbed phosphogypsum building solid waste, and belongs to the technical field of building backfill engineering. After undisturbed phosphogypsum is scattered, the undisturbed phosphogypsum is mixed with the water reducing agent, the water, the ground phosphate rock, the alkaline activator, the filler and other raw materials in the first stirring equipment according to a specific proportion and in a specific adding mode, and the large-flow-state backfill material is formed. Wherein the carbide slag and the red mud in the phosphogypsum and the alkaline exciting agent can adopt original-state water-containing slurry slag, and drying and grinding treatment is not needed. The utilization rate of solid waste in the backfill material prepared by the method reaches 95% or above, a large amount of phosphogypsum and building solid waste can be consumed, and the backfill material has good social and economic benefits, and is simple in production process flow and wide in application range.
