Fineness of Cement - Construction How

An increase in fineness increases the amount of gypsum required for proper retardation because, in a finer cement, more C3A is available for early hydration. The water content of a paste of standard consistency is greater the finer the cement, but conversely an increase in fineness of cement slightly improves the workability of a concrete mix. This anomaly may be due partly to the fact that ...
