Soundness Test:
Expansion of cement is measured/computed by a soundness test. Soundness means the ability to resist volume expansion and it is an indication of durability.
The unsoundness in cement is due to the presence of an excess of free lime that could be combined with acidic oxide at the kiln.
The soundness of cement may be determined by two methods, namely the Le-Chatelier method and the autoclave method.
The Le-Chatelier test detects unsoundness due to free Lime only. This method of testing does not indicate the presence and after effect of the excess of magnesia.
As per Indian Standard specification, if the content of magnesia is greater than 3% in cement then Autoclave Test is performed which is sensitive to both Lime and Magnesia.
