Free lime content in slag was investigated using a solution calorimetric technique in order to clarify hydration behavior of the free lime. After confirmation of the agreement between the heat of hydration of pure CaO obtained by this method and the calculated value, the heats of hydration of slags with different free lime contents were measured. Good correlation between the free lime contents and the heats of the hydration was indicated though small amounts of calcium silicates, calcium aluminates, MgO and calcium ferrite in the slags might be hydrated in addition to the free lime.
