For conventional concrete the fineness modulus of the fine aggregate should range from 2.3 to 3.1. A higher fineness modulus represents a coarser material and a lower fineness modulus represents a finer material. Knowing the fineness modulus of aggregate gives you some indication of the amount of paste needed to make concrete using the aggregate.

Read MoreApr 07, 2020· However, the sieve test gives no information on the size of grains smaller than 45 μm (No. 325 ASTM) sieve, and it is the finer particles that play the greatest part in the early hydration.; For this reason, modern standards prescribe a test for fineness by determination of the specific surface of cement expressed as the total surface area in square metres per kilogram.

Read MoreFINENESS TEST ON CEMENT. Piratical size of the cement is directly affecting the strength of the concrete. Finer partials react very quickly than the comparatively large particles. Further, fine cement has a greater surface area and hence faster the development of strength. There are two methods of testing of fineness of cement. By sieving
