The decomposition of tricalcium silicate in the temperature range, 1,000 degrees-1,300 degrees C

Abstract

The decomposition of tricalcium silicate, 3CaO.SiC>2, into dicalcium silicate and free lime, has been studied in the temperature region 1,000-1,300C. The extent of decomposition, measured by means of free-lime determinations, was found to be greatest at about 1,175C. After a day's heating at this temperature the de- composition was about fifteen times as great as after a day's heating at 1,000C.
