Which test is commonly used to determine the fineness of cement?
Correct Answer: Blaine air permeability test
- Step 1: Understand that the fineness of cement refers to the size of the cement particles.
- Step 2: Learn that smaller particles have a larger surface area, which can affect how the cement performs.
- Step 3: Know that the Blaine air permeability test is a method used to measure this surface area.
- Step 4: In the Blaine test, air is passed through a sample of cement.
- Step 5: The amount of air that passes through the cement sample helps determine how fine the particles are.
- Step 6: A higher surface area indicates finer cement, while a lower surface area indicates coarser cement.
