Fineness Test Of Cement

Fineness of Cement

 · However, the sieve test gives no information on the size of grains smaller than 45 μm (No. 325 ASTM) sieve, and it is the finer particles that play the greatest part in the early hydration.; For this reason, modern standards prescribe a test for fineness by determination of the specific surface of cement expressed as the total surface area in square metres per kilogram.
