Ordinary Portland Cement: Uses, Advantages
Excess magnesia makes the cement unsound. Sulphur Trioxide: Excess quantity of sulphur trioxide also makes the cement unsound. Alkalies: The large quantity of alkalies causes efflorescence. Cement with lower alkali content has caused objectionable expansion. Gypsum: During the grinding process, a small quantity of gypsum is added.

2 天前 An excess amount of magnesia may make the cement unsound and expansive, but a little amount of it can add strength to the cement. Production of MgO-based cement also causes less CO2 emission. All cement is limited to a content of 6% MgO. Sulphur trioxide Sulfur trioxide in excess amount can make cement

2012-12-1 Super sulfate cement is made by grinding a mixture of 80–85% selected GBFS with 10–15% calcium sulfate and about 5% of Portland cement clinker. It is generally used where high sulfate, acid and organic oil attacks on a structure are expected. Again the cost of this type of cement is high, due to the limited availability of materials.
