Steel slag composite material for 3D printing as well as preparation method and application of steel slag composite material

Abstract

The invention discloses a steel slag composite material for 3D printing as well as a preparation method and application thereof, and relates to the technical field of civil engineering materials. The steel slag composite material for 3D printing comprises a solid component and a liquid component, and the solid component comprises steel slag and the like. The steel slag and the steel slag powder are added into the 3D printing building material in a large mixing amount for building printing, the steel slag powder replaces a cement binding material, and the steel slag replaces fine aggregate, so that on one hand, comprehensive resource utilization of solid waste is guaranteed, the building cost is greatly reduced, exploitation of river sand is reduced, and damage to the environment is reduced; and on the other hand, domestic steel slag inventory can be greatly consumed, the maintenance cost and the like of enterprises on the steel slag are reduced, waste is turned into wealth, the cost is turned into value-added benefits, and profits and values can be created for the enterprises.

Description

technical field [0001] The invention relates to the technical field of civil engineering materials, in particular to a steel slag composite material for 3D printing, a preparation method and an application thereof. Background technique [0002] The output of steel represents a country's level of industrial development. Before 1996, the world's leading steel-producing countries were the United Kingdom, the United States, the Soviet Union, and Japan. Since 1996, China's steel output has been the world's largest for 24 consecutive years. At present, China's crude steel production capacity exceeds 100 million yuan and is the only country in history that accounts for 50% of the total. The time span of my country's steel leadership in the world will exceed that of the United Kingdom and the United States. Possibly a hundred years. The steel slag produced by steel mills is mainly landfilled at will, and a small amount is comprehensively utilized. A large amount of steel slag is ill...

Problems solved by technology

However, China's current comprehensive utilization status is far from this plan, especially the utilization rate of converter steel slag known as "inferior cement clinker" is only 10% to 20%.

The steel slag produced by domestic iron and steel enterprises cannot be disposed of in time, resulting in a large amount of steel slag occupying land and polluting the environment
