HALDCEMT........The Portland Cement data of Hald(1952), p647
3CA = Proportion of 3CaO.Al2O3 in the mixture.
3CS = Proportion of 3CaO.SiO2 in the mixture.
4CAF= Proportion of 4CaO.Al2O3.Fe2O3 in the mixture.
2CS = Proportion of 2CaO.SiO2 in the mixture.
HEAT = Heat Evolved in Drying
Note: Each proportion appears to be rounded down to the
nearest full percentage point; but X1+X2+X3+X4
varies "only" from 95 to 99.
