Blaine fineness. 1. n. [Drilling Fluids] The particle size or fineness of a cement in cm 2 /g or m 2 /kg, usually determined from air permeability tests using a device known as a Blaine permeameter. Fineness affects the hydration rate (setting) and the requirements for the amounts of water, retarder, and dispersant.Web
