Abstract

The invention provides a low-carbon active ligand and a slag powder cementitious material thereof. The invention is characterized in that bauxite, glauberite, fluorite, gypsum, garnets and a plurality of ores are ground and prepared into low-carbon negative and positive ligands respectively; the negative and positive ligands are ground, mixed and prepared into the low-carbon active ligand; the low-carbon active ligand is added to slag; and a low-carbon slag powder cementitious material used to replace cement is obtained after homogenization. As no calcination process is adopted, the problem of atmospheric pollution during cement production is solved (because calcination is not needed); the slag (steel slag, water granulated slag, fly ash and the like) can be utilized well; mineral resources (without limestone) can be protected; and energy can be saved (only 'two-grinding and one-calcination' needs to be changed into 'one grinding'). Moreover, the slag powder cementitious material has good physical performance indexes and can be widely applied in roads, bridges, buildings, cement precast parts and other concrete construction.

Description

Technical field:

[0001] The invention belongs to the field of building materials, and in particular relates to a low-carbon active ligand and a low-carbon slag micropowder gelling material Background technique:

[0002] Since Portland cement was invented by British mason Joseph Aspadian in 1824, people have been using limestone (CaCO 3 ) and coal are produced using the "two grinding and one burning" production process, which is still used so far, resulting in the depletion of mineral resources, the deterioration of the atmospheric environment, and the shortage of industrial energy. Invention content:

[0003] The purpose of the present invention is to provide a low-carbon active ligand and low-carbon slag micropowder cementitious material that does not require limestone and coal, and does not need to be calcined in the production process.

[0004] The gist of the invention is that firstly, the three materials of bauxite, gypsum and garnet are added to a ball mill in a rat...
