Hydration Of Tricalcium Aluminate (C3A) In The Presence And Absence Of Gypsum—Studied By Raman Spectroscopy And X-Ray Diffraction - Journal Of Materials Chemistry (Rsc Publishing) from pubs.rsc.org

Psc is a refined calcium silicate cement of which the major chemical constituents are tricalcium silicate (3cao•sio 2; C4af), with specific ratios of each component. Even though it represents less than 10% of the total composition, its strong reaction with water can lead to a rapid setting, called flash set.

Raman spectroscopy has been used to follow the hydration of one of the principal components of ordinary portland cement (opc) clinkers, tricalcium aluminate, both in the absence and in the presence of calcium sulfate. The reduction of sulphate salts lowers the possibility of sulphate attack on the concrete.

Generates less heat of hydration c. C4af), with specific ratios of each component. Sulphate resisting cement is a type of portland cement in which the amount of tricalcium aluminate (c3a) is restricted to lower than 5% and (2c 3a +c4af) lower than 25%, which reduces the formation of sulphate salts.
