3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Portland cement clinker by the appropriate ingredients, adding the right amount of natural gypsum for ground water made in nuclear power engineering rigid gel
material.
4 material requirements
4.1 Nuclear cement clinker
Tricalcium silicate (C3S) content by mass fraction does not exceed 57%, tricalcium aluminate (C3A) content by mass fraction does not exceed
7%, of free lime (f-CaO) content of the mass fraction of not more than 1.0%.
Calculate various mineral composition according to the chemical composition, mineral composition is only theoretically possible content generation.
When m (Al2O3)/m (Fe2O3) > 0.64, the mineral composition according to formula (1), (2) Calculated.
w (C3A) = 2.65 × w (Al2O3) -1.69 × w (Fe2O3) (1)
