Mineral structure of cement clinker
The invention discloses a mineral structure of cement clinker. A structure inducer is directly mixed in raw materials in proportion as a raw material component and the materials are calcined by adopting a novel dry-process kiln. In the clinker obtained after calcination, the sizes of tricalcium silicate crystals are 40-200mu m and the sizes of dicalcium silicate crystals are 2-25mu m. The structure inducer is selected from natural gypsum, anhydrite, fluorapatite, copper slag, steel slag, zinc slag, nickel slag, phosphorus slag, flyash or a composite thereof. The mixing amount of the structure inducer is 0.1-5% compared with that of the cement raw materials. Compared with ordinary Portland cement, the mineral structure of the cement clinker, which is provided by the invention, has the advantages that the size of tricalcium silicate is larger and the size of dicalcium silicate is smaller, thus reducing the energy consumption in the clinker grinding process and improving the activity and strength of cement in the cement hydration process.
