Study on the palletizing
process for the use of phosphorous gypsum as cement retarder |
| |
| Abstract: | Effect of the pre－ processing method of phosphorous gypsum on the performance of cement was studied. The results indicate that phosphorous gypsum neutralized with lime can be used as retarder for Portland cement and slag Portland cement. The fired phosphorous gypsum is applicable for fly－ ash Portland cement. The palletizing process with slaked lime, cement clinker and calcined plaster as additive was also introduced. |
