fineness test for gypsum

What is the Fineness of Cement

Apr 12, 2021Conclusion: Blaine air permeability test of cement is important since it gives an idea of the size of smaller grains of the particles which play a major role in the process of hydration and strength development of the cement. Wagner's turbidimeter test. Aim: To determine the fineness of cement by Wagner's turbidimeter test.
