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.
