Menossi11 found that the fineness modulus used in experimental work was equal to 2.48, very close to the value obtained with natural sand. Schumacher12 obtained a fineness modulus value equal to 2.77 for the stone dust, while with river sand it was equal to 2.11. In this way, it is clear the relationship between the employment conditions of the
Oct 14, 2016 The value is not equal to the average particle size, but it can accurately reflect the thickness of sand. The larger the fineness modulus, the thicker the fine aggregate. Common concrete sand has a fineness modulus ranging from 3.7 to 1.6, preferably medium sand, or coarse sand plus a small amount of fine sand in a ratio of 41.
The fineness modulus crushed stone dust is 2.2 to 2.6 as same as that of sand and specific gravity is 2.4. Due to utilization of crushed stone dust we can reduces the cost of construction at the same time we try to solve the problem on disposal of crushed stone dust because of the waste material generated in crusher the manufacturer collected ...
Fineness modulus of fine aggregate is 2.75. It means the average value of a and 3 sieve. It means the average aggregate size is in between 0.3mm to 0 Values of Fineness Modulus of Sand Fineness modulus of fine aggregate varies from 2.0 to 3.5mm.
Fineness modulus of fine aggregate varies from 2.0 to 3.5mm. Fine aggregate having fineness modulus more than 3.2 should not considered as fine aggregate. Various values of fineness modulus for different sands are detailed below. Type of sand Fineness modulus range Fine sand 2.2 2.6 Medium sand 2.6 2.9 Coarse sand 2.9 3.2
Stone dust improves pozzolanic activity in concrete along with filling voids by better pack-ing and improves concrete durability.The fineness modulus of rock dust is in the range of 2 to 2.2 as compared to 2.4 to 2.6 for fine sand. This study aims at using stone dust as partial replacement of sand in concrete to study its effects on
using Crushed stone dust as well as natural river sand. The following tests were performed 1. Physical properties like bulk density, fineness modulus etc., grain size distribution for Crushed stone dust and natural river sand 2. Mortar and masonry characteristics using Crushed stone dust and river sand a. Compressive strength of mortar b.

Jul 02, 2020 The stone dust and ceramic waste are the replacements of natural sand and stone respectively. The developed composite is tested for various mechanical testing to know the strength under compression, flexural and shear. Seven different types of samples were casted by varying the stone dust from 0 to 100 in the interval of 20.

Jan 01, 1994 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. Before calculating FM, lab technicians perform a sieve analysis to determine the particle size distribution, or grading, of the aggregate sample.
range of 10 - 100. ... Properties Result value Fineness Modulus 10 mm Aggregate 10mm CA 5.956 ... Fineness modulus and Specific gravity of stone dust were 2.60 and 2.40 respectively. Particle ...
b As per the grading given in Table 1, the fineness modulus of sand could vary from I.2 to 2.2. However, it is preferable to have minimum fineness modulus of l-4 in case of crushed stone sands and crushed gravel sands and a F. M of 1 5 in case of naturally occurring sands. Hence,
For normal concrete, the sands fineness modulus range is 2.3-3.1Pofale amp Quadri, 2013. As a result, there is a scarcity of sand. ... Cg value of sand and stone dust is 5.67 and 1.22 ...
Jul 31, 2016 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 modulus.
ired grading Zone II and fineness modulus 2.4 to 3.1 can also be achieved consistently in the case of stone dust. Processed stone dust can improve both strengthand flexural through better bond compared to river sand. of Stone dust 1. Have no impurities like silt, clay and pebbles. 2.
