Test to Check Fineness of Cement

Test to Check Fineness of Cement FINENESS so we need to determine the fineness of cement by dry sieving as per IS: 4031 (Part 1) – 1996.The principle of this is that we determine the proportion of cement whose grain size is larger than specified mesh size.

6. FINENESS OF CEMENT - Course Hero

FINENESS OF CEMENT Aim: To determine the fineness of cement sample. Practical Relevance: Finer the cement (rate of reaction is more) hydration is more and strength is more. Therefore, the rate of reaction and strength depend on fineness of cement finer the cement strength is more and vice-versa. To have the same rate of hardening in different brand of cement the fineness has been standardized.
