Physical

1.Compressive strength (Kgs./cm2) at 3,7 & 28 Days

2.Setting Time (minutes) Initial & Final

3.Expansion (a) Le-chatlier mm for early expn.(b) Autoclave % for delay expn.

4.Fineness (Blaines) cm2/gm.

Chemical

Lime saturation factor = LSF = 100(CaO + 0.75Mg) / (2.85SiO2) + (1.18Al2O3) + (0.65Fe2O3)
For MgO below 2%
Lime saturation factor = LSF = 100(CaO + 1.5Mg) / (2.85SiO2) + (1.18Al2O3) + (0.65Fe2O3)
For MgO above 2%

It means determination of Major oxides (1.silica 2.Alumina 3.Iron 4.Lime 5.Magnesia) and Minor oxides (6.Mangnese 7.Sodium 8.Potasium 9.Sulphur).

So, Physical 5 nos.and Chemical 9 nos. Total 14 Tests.
