Abstract

The invention provides a metallurgy-based solid waste reinforcing material and a preparation method, and belongs to the technical field of building materials, the metallurgy-based solid waste reinforcing material comprises: 30%-50% of a cementing curing component, 10%-20% of a mineral stabilizing component, 60%-75% of a structure stabilizing component, and 5%-10% of a mineral fluidity adjusting component; wherein the cementing curing component, the mineral stabilizing component, the structure stabilizing component and the mineral fluidity adjusting component all contain 50% or above of metallurgy-based solid waste materials, and the utilization amount of the overall metallurgy-based solid waste materials is larger than 90%. According to the metallurgy-based solid waste reinforcing material provided by the invention, the building structure reinforcing material is mainly prepared from the metallurgy waste as a raw material and is used for reinforcing and repairing a building structure, the problem of environmental pollution can be effectively solved, and the recycling amount of the metallurgy solid waste can be increased.

Description

technical field [0001] The invention belongs to the technical field of building materials, and more specifically relates to a metallurgical solid waste reinforcement material and a preparation method thereof. Background technique [0002] The by-products of sintering flue gas desulfurization and denitrification in the iron and steel industry have the characteristics of complex composition and instability, making resource utilization difficult. With the proposal of ultra-low emission of flue gas in the iron and steel industry, the amount of new denitrification by-products is gradually increasing, and even the by-products of oxidation and denitrification make the composition of desulfurization ash more complicated, and the processing difficulty is further increased. Mainly focus on the following two aspects: (1) Calcium sulfite in desulfurization ash is unstable, easy to decompose when heated, and easily cause secondary pollution. In addition, the decomposed calcium oxide is ...
