    Fine Aggregate and Fineness Modulus. 2016-10-14. In civil engineering, aggregates with a particle size greater than 5 mm are coarse aggregates, also known as stone; aggregates with a particle size of less than 5 mm are fine aggregates, also known as sand.Qualified fine aggregate should have a good gradation, including fineness modulus, firmness, mud content, sand equivalent, etc.

    As the fineness modulus factor increases, the aggregate gradation becomes coarser. Fineness modulus is calculated by dividing by 100 the sum of the cumulative percents retained on specified sieves. For fine aggregates, the fineness modulus ranges from 2.00 to 4.00, while coarse aggregates range from 6.50 to 8.00, when all material is finer than 1-1/2 in. (38.1 mm). Combined gradations will ...

    Fineness Modulus - an overview | ScienceDirect .

    Aggregates which mainly pass a 4-mm sieve are termed 'fine' aggregates. The coarseness or fineness of sands is described by d/D sizes in mm of 0/1, 0/2 and 0/4. A further classification is provided based on either the percentage passing a 500-μm sieve (Table 15.7) or the fineness modulus, for coarse, medium and fine grading sands (C, M and F).

    THE ROLE OF FINENESS MODULUS - Southport .

    To determine the fineness modulus, the contractor adds the cumulative percentage-retained values and divides the sum by 100. This process must be repeated for both coarse and fine aggregate sizes. Once the fineness modulus of each size has been determined, they can be combined by means of a special equation to determine the proportions necessary for creating the desired concrete.

    The fineness modulus of the fine aggregate is required for mix proportioning, since sand gradation has the largest effect on concrete workability. Concrete made with a fine sand (low fineness modulus) has much higher paste requirements for good workability.
