| titleOfInvention | Portland cement made from self-pulverized clinker and slag and preparation method for Portland cement |
| abstract | The invention belongs to the technical field of building materials, and particularly relates to a Portland cement made from self-pulverized clinker and slag and a preparation method for the Portland cement. The Portland cement made from the self-pulverized clinker and the slag is characterized in that the Portland cement is made from the slag, plaster and the self-pulverized clinker by means of mixing and comprises 57%-87% of the slag, 3%-18% of the plaster and 1%-30% of the self-pulverized clinker in weight percent. The self-pulverized clinker is prepared according to the steps of preparing cement raw materials by means of arbitrary combination of the lime saturation coefficient ranging from 0.589 to 0.823, the silica ratio ranging from 2.5 to 4.0 and the alumina ratio ranging from 1.0 to 2.8 of the clinker; and grinding the cement raw materials to the degree with screen residues smaller than 18% by means of sieving of a sieve with the 0.08mm side length of a sieve mesh, calcining the grinded cement raw materials for 0.5 hour to 1.5 hours at the high temperature ranging from 1200 DEG C to 1380 DEG C prior to slowly cooling to the room temperature with the cooling rate of 15-45 DEG C /min, and obtaining the self-pulverized clinker. The method is simple in process, low in calcining temperature and low in grinding power consumption, and carbonization resistance of the Portland cement can be improved by the method. |
