Background
The steel slag is an industrial byproduct generated in the steel-making process, and the generation rate of the steel slag is about 8-15% of the doping amount of the crude steel. In recent years, the steel slag yield of China is rapidly increased along with the development of the steel industry, however, the resource utilization rate of the steel slag produced by steel enterprises of China is only 30-40%, most of the steel slag cannot be effectively utilized and treated, and the steel slag cannot be comprehensively utilized due to the adoption of a stacking mode, so that the problems of environment pollution, land occupation, resource waste and the like are caused, and the steel slag is urgently recycled.
Numerous studies have shown that steel slags, especially high-basicity converter slags, have a chemical and mineral composition similar to that of cement clinker, containing a large amount of silicate minerals, a small amount of aluminates and aluminoferrite minerals, which have the ability to react with hydration, thus giving steel slags certain hydraulic properties. However, the hydration activity and solubility of the steel slag are relatively poor, and the steel slag has poor gelation property only caused by the hydration of the steel slag under the common condition, so that the application of the steel slag is limited.

The preparation method of the steel slag-based alkali-activated cementing material comprises the following steps:
(1) fully mixing the ground steel slag powder, the ground aluminum ash slag powder, the fly ash, the slag powder and the silica fume to obtain a mixture A;
(2) dissolving a solid excitant in water to obtain an alkali excited solution B;
(3) and (3) fully and uniformly mixing the mixture A obtained in the step (1) and the alkali-activated solution B obtained in the step (2) to obtain a target product.
The steel slag-based alkali-activated cementing material provided by the invention can be used for manufacturing low-strength alkali-activated steel slag-based concrete or used as a cementing material by mine filling.

The steel slag-based alkali-activated cementing material can be used for recycling steel slag resources and utilizing the steel slag resources on a large scale, and effectively solves the problems of land occupation and environmental pollution caused by the current steel slag stacking.
As sodium hydroxide, sodium silicate and the like are used as alkaline activators, the glass body in the slag and the fly ash can be promoted to break, the dissolution of active components in the slag and the Ca (OH)2 generated by the hydration of the steel slag can be promoted to react, and more calcium silicate hydrate gel (C-S-H) can be generated.
Meanwhile, a small amount of aluminum ash can introduce more Al2O3 into the system, and the addition of the aluminum ash under the alkaline condition can promote the breakage of Al-O bonds, increase the generation of Ca-Si-O-H and Ca-Al-Si-O-H gels, improve the compactness of the internal structure and improve the mechanical property of the material.
The addition of the silica fume can react with Ca (OH)2 generated by hydration of dicalcium silicate and tricalcium silicate in the steel slag and Ca (OH)2 generated by reaction of free CaO and water to generate stable hydrated calcium silicate and hydrated calcium aluminate, thereby improving the strength of the material and eliminating the expansion hazard brought by free calcium oxide in the steel slag.
