Calculate Contraction
L1 = Seperation of Test Marks on Sample in Initial State L2 = Seperation of Test Marks on Sample in Final State
Calculate Moisture Content
W1 = Wet Weight W2 = Weight of Sample after drying at 110°C
Calculate Loss On Ignition
W1 = Wet Weight W2 = Dried Weight W3 = Weight of Sample after Heating to about 1000°C
