Hydrated lime itself, i.e. calcium hydroxide, is very much finer than those impurities, having a specific surface area of around 1.3 m2/g, compared with Portland cement which is about 0.4 m2/g. So a Fineness Test can be used, passing the lime through a fine mesh sieve, and a good quality lime hydrate should have not more than about 1% retained
