Determined via air-permeability tests (Blaine fineness). Finer cement (like Type III) hydrates faster, accelerating strength gain.
The standard limits specific compounds as a function of cement type, including tricalcium aluminate ((C_3A)), tricalcium silicate ((C_3S)), and sulfates ((SO_3)), to control properties like sulfate resistance and setting time. astm c150 c150m22 pdf verified
