Effects of various fineness moduli of fine aggregate on engineering properties of high‐performance concrete

The effects of various fineness moduli (FM) of fine aggregate on the engineering properties of high‐performance concrete (HPC) were studied. Two kinds of coarse aggregates (stiff and soft) and three kinds of fine aggregates (FM=3.24, 2.73 and 2.18) were used.

Concrete Mix Design- A modification of the Fineness Modulus

A comparison of three maximum size gradings of sand-gravel and sand-crushed stone mixtures in concrete has revealed that for each type and size of coarse aggregate a constant value for fineness modulus will be obtained for any workable mixture from lean to rich, if the cement is included in the modulus figures.

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. For instance, sand with a low fineness modulus has more voids in it and more particle surface ...

Fineness Modulus Method of Concrete Mix Design

Fineness Modulus Method of Concrete Mix Design The index number, which describes the relative sizes of coarse and fine aggregates, is called as fineness modulus (FM). Fineness modulus is determined separately by sieving coarse and fine aggregates through the following set of sieve. IS sieves for coarse aggregates are 80 mm, 40 mm, 20 mm, […]
