Fineness Modulus (FM) is an empirical calculation used to support the optimisation of a concrete mix design.
Experimental results show that when fineness modulus of sand decreases, both water demand and
The fineness modulus of sand is a value that indicates the coarseness or fineness of sand particles. It is commonly used in the construction industry to determine the amount of sand to be used in concrete mixtures, as well as to ensure consistency and quality of the sand used in construction
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
For fine aggregate used in concrete, the FM generally ranges from 2.3 to 3.1 as called for in ASTM C 33, but in some cases, fine sands are used with an FM less than 2.0 (for example, some Florida deposits) and in other cases, a coarser fine aggregate with an FM higher that 3.1 (for example, some western coarse sands or manufactured fine
At the proportion of sand 30%–40% the mixture becomes harsh and segregation occurs resulting in a decrease in compressive strength of concrete. In the proportion of sand 43.5%–55% the consistency of the mixture has decreased but is still workable so that the compressive strength of concrete
To investigate the effect of changes in sand fineness modulus (FM) on the fresh and hardened properties of SCC and SCLC, an experimental investigation with twelve mixtures was designed. Two series of mixtures were used, each with two coarse aggregate types: Light Expanded Clay Aggregate (LECA) and natural
Objectives • Evaluate the effects of gradation, fineness modulus and mineral constituents of various natural sands on strength of hardened concrete. • Develop an optimization technique to optimize the grain size distribution and fineness modulus of fine sands and to make them suitable for concreting works. â
The fineness modulus of the sand used in ordinary concrete is within 3.7 1.6. And if Mx is within 3.7 3.1, it is coarse sand; if Mx is within 3.0 2.3, it is medium sand; if Mx is within 2.2 1.6, it is fine sand; and if Mx is within 1.5-0.7, it is superfine sand which should be considered specifically when concrete is
Determines sand properties such as Fineness Modulus, Specific Gravity, Bulking of Sand, Compressive strength, and Silt and clay content, which is best for mortar and concrete work or suitable for plastering and finishing
Fineness Modulus (FM) is an empirical calculation used to support the optimisation of a concrete mix design. It is used to determine ‘degree of uniformity of the grading’. This can create a relationship between grading and consistence and/or the
Experimental results show that when fineness modulus of sand decreases, both water demand and segregation of fresh concrete are increased. The increments can be cut down by increasing water-reducing admixture dosage and using an
