What is the fineness of the cement?
There are two common methods used to determine the fineness of cement. They are, namely: The Blaine air permeability test ; The sieving method. The Blaine air permeability test involves determining the specific surface area by measuring the fineness of hydraulic cement. The specific surface area is the total surface area of all the cement ...
Influence of cement fineness on the performance of …
The fineness of cement is tested using a Blaine air permeability apparatus according to ASTM C204, (2023) 'Standard Test Methods for Fineness of Hydraulic Cement by Air-Permeability Apparatus'. The test results are presented in Table 1, indicating that as the cement fineness increases, the specific surface area also increases.
