ASTM C115/C115M-10e1 PDF Download

The ASTM C115/C115M-10e1 standard is a test method that is used to determine the fineness of Portland cement. Fineness refers to the measure of specific surface area of the cement. This standard utilizes the Wagner turbidimeter to calculate the specific surface area of the cement in square centimeters per gram or square meters per kilogram.

This standard is important because the fineness of cement has significant effects on its performance in concrete. It is a critical factor that affects the strength, workability, and durability of the final concrete product. By determining the fineness of Portland cement using the Wagner turbidimeter, this test method ensures that the specific surface area is calculated accurately and consistently.
