Cement is a binding material used with fine aggregate to produce mortar for masonry, or with sand and aggregates to produce concrete. Construction cements are usually comprised of lime or calcium silie and combined with fly ash. They are egorised as either hydraulic (E.g. Portland cement) or nonhydraulic, depending on their ability to set in water.

To determine the fineness of cement by dry sieving as per IS: 4031 (Part 1) – 1996. Principle. The fineness of cement is measured by sieving it through a standard sieve. The proportion of cement, the grain sizes of which, is larger than the specified mesh size is thus determined. Apparatus. i) 90μm IS Sieve.
Portland cement is manufactured by crushing, milling, and blending selected raw materials containing appropriate proportions of lime, iron, silica, and alumina. Most Portland cement particles are less than 0.045 mm (No. 325 sieve) in diameter. Portland cement combined with water forms the cement paste component of the concrete mixture.
2. After sieving, the cement must be removed from the bottom surface of the sieve gently. 3. Weighing machines must be checked before use. Conclusion. Compare your values with standard values from the type of cement used and give your comments on the suitability of using cement samples for construction purposes. ALSO READ

What Is Fineness Modulus of Sand? Fineness modulus of sand (fine aggregate) is an index number which represents the mean size of the particles in sand. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fineness modulus.
