摘要: | This paper-discusses the basic concept of steam hydration and presents test data oil heat of hydration by exposing cement compounds to pressurized steam. The lest samples include cement and its individual compounds; tricalcium silicate (C3S), dicalcium silicate (C2S), tricalcium aluminate (C(3)A), and tetracalcium aluminoferrite (C(4)AF). For a compacted 10 grams C3S sample, the heat of hydration was determined as 209 cal/g. All samples except C;A hardened during steaming. Nonetheless, rite C(3)A samples reacted very rapidly with steam and registered a 91 C temperature rise during the test. This paper also discusses effects of sample's fineness and degree of compaction on heat evolution and hydrate morphology during exposure to steam. The test results verify the validity of the dry-mix/steam-injection (DMSI) concept. |
