Portland Cement Fineness Pavement Interactive
Portland Cement Fineness Fineness, or particle size of portland cement affects hydration rate and thus the rate of strength gain. The smaller the particle size, the greater the surface area-to-volume ratio, and thus, the more area available for water-cement interaction per unit volume.
This test method covers hydraulic cement fineness tests performed using a sieve. The sieve frame should be made of a circular metal matching the specified dimensions, fitted with either a stainless steel woven-wire sieve cloth or an electroformed forced nickel sieve sheet.
