ROBO sand: ROBO sand or crusher dust obtained from local granite crushers was used in concrete to cast the cubes and cylinders. The bulk density of ROBO sand or crusher dust is 1768 kg/m3. The specific gravity and fineness modulus of ROBO sand are 2.66
The fineness of aggregates is measured using the fineness modulus (FM). The FM for fine aggregates should be within the range of 2.3 to 3.1. Aggregates that are too fine will have a high water demand, and will also result in a sticky concrete mix.
70% sand with the remainder being gravel. The fineness modulus of the sand and gravel used varies from region to region. Product densities usually range from 135 pounds to 145 pounds per cubic foot. Admixtures are often used to increase concrete strength
Abstract 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.
Coarse aggregate means the aggregate which is retained on 4.75mm sieve when it is sieved through 4.75mm. To find fineness modulus of coarse aggregate we need sieve sizes of 80mm, 40mm, 20mm, 10mm, 4.75mm, 2.36mm, 1.18mm, 0.6mm, 0.3mm and 0
normalweight sand, a wide range of concrete densities may be obtained. Aggregates for structural lightweight concrete usually have a top size of minus 3/4 in. or minus 1/2 in. Most lightweight concretes use a lightweight coarse aggregate 3/4 in. to #4 mesh (1/2 - #8) with ordinary sand, minus #4 mesh (minus 4.8 mm), however other combinations of

3.2. Based on Fineness Modulus As per IS 1542: 1992 – clause 5.2, the fineness modulus of sand shall be not less than 1.4 in case of crushed stone sands and crushed gravel sand and not less than 1.5 in case of naturally occurring sands. Lower FM indicates fine sand and higher FM indicates courser sand. 4. Result interpretation 4.1.
The fineness modulus of sand was calculated as 2.41 using sieve analysis following ASTM C136 . The table also indicates that grain size of the raw materials is approximately equivalent to the d 10 , d 50 and d 90 that are used to determine the size of a particle.

And the fine aggregate used was river sand with a fineness modulus of 2.8. Mechanical properties of recycled concrete in marine environment The fine aggregate used was provided from local river with a fineness modulus of 2.7.
In recent years, the construction industry has been faced with a decline in the availability of natural sand due to the growth of the industry. On the other hand, the metal casting industries are being forced to find ways to safely dispose of waste foundry sand (FS). With the aim of resolving both of these issues, an investigation was carried out on the …

Portland cement concrete may be mixed at the plant, at the placement site or in transit, depending upon the type of mixing and delivery system that is used. The Plant Inspector's responsibility is limited to inspecting the operations that take place at the plant. Once the mixer or haul unit departs
Granulated blast furnace slag is a waste of steel industry; its use can be best exploited as part replacement of sand in concrete. It can replace sand to the amount of 70 % in concrete mixes. Its Availability is limited, restricted to steel plant area.

In 1925, Duff Abrams introduced the concept of fineness modulus (FM) for estimating the proportions of fine and course aggregates in concrete mixtures. The premise: "aggregate of the same fineness modulus will require the same quantity of water to produce a mix of the same consistnecy and give a concrete of the same strength."
Oct 17, 2012 · In case of blended aggregate with CS of mixing ratio of below 50 %, its particle size distribution met the standard range even the fineness modulus was relatively high. This is because consumer’s demand that they want to use CS with natural sand of low fineness modulus was reflected.
