Method for secondarily synthesizing calcium sulphoaluminate mineral in portland cement clinker |
| abstract |
A method for secondarily synthesizing calcium sulphoaluminate mineral in Portland cement clinker is provided. The method includes adding plaster into raw Portland cement and calcination, then heating twice to re-form calcium sulphoaluminate mineral that is decomposed at high temperature in the clinker. This method can increase the content of calcium sulphoaluminate mineral in the clinker, sufficiently exert the advantages of the calcium sulphoaluminate mineral in the clinker, enhance the early stage performance and long-term performance of the cement clinker, and increase the quantity of mixture in the cement. |
