The invention relates to the technical field of cement, in particular to a quick-drying cement clinker. The quick-drying cement clinker uses limestone as a main material, and comprises in parts by mass: 100-125 parts of limestone, 22-43 parts of coal ash slag, 2-10 parts of a quick-drying agent, 10-15 parts of an epoxy ester, and 10-25 parts of a mixed material, wherein the effect of the quick-drying cement clinker which comprises 108 parts of limestone, 30 parts of coal ash slag, 5 parts of the quick-drying agent, 10 parts of the epoxy ester and 18 parts of the mixed materials is the best. After adopting the above formulation, the overall stability of the cement clinker is well improved by the epoxy ester, in addition, the bonding force of the cement clinker is well enhanced by the mixedmaterial, and the overall performances of the cement clinker are improved.
Description
technical field [0001] The invention relates to the technical field of cement, in particular to quick-drying cement clinker. Background technique [0002] Cement clinker is a semi-finished product obtained by using limestone, coal ash, and iron raw materials as the main raw materials, which are prepared into raw meal in an appropriate proportion, burned until partially or completely melted, and cooled. In the cement industry, the most commonly used Portland cement clinker is mainly composed of calcium oxide, silicon dioxide and a small amount of aluminum oxide and iron oxide. The main mineral composition is tricalcium silicate, dicalcium silicate, tricalcium aluminate and tetracalcium aluminoferrite. Portland cement clinker and appropriate amount of gypsum are ground together to form Portland cement. [0003] Chinese invention patent CN103011633A discloses a cement clinker, the cement clinker is made of raw materials in the following weight ratio: limestone 75-85; carbide ...
