Which test is used to determine the fineness of cement?

Step 1: Understand that the fineness of cement refers to the size of the cement particles.
Step 2: Know that smaller particles have a larger surface area, which can affect how the cement performs.
Step 3: Learn about the Blaine air permeability test, which is a method used to measure the surface area of cement particles.
Step 4: In the Blaine test, air is passed through a sample of cement, and the resistance to the air flow is measured.
Step 5: The results from the test help determine how fine the cement is, based on how much surface area the particles have.
