Seven types of river sands (K 1 –K 7) were designed with a different fineness modulus. Sand gradations of river sands and standard sand (K s) were divided into three categories according to GB/T 14684-2011 , which were shown in Table 3. The fineness modulus was used to characterize the fineness and coarseness of the sand.Leave Us Now

Jan 01, 2021 To achieve the goals, the following materials were used: Portland cement CEM I 42,5H – Asia Cement – Nikolsk city; sand of the Aleksandrovsky open pit with the fineness modulus M kr = 1,4; ground quartz sand of the Alexander quarry with a specific surface S sp = 1800 – 2000 cm 2 /g; dolomite flour (DF) - (quarry Ardon North Ossetia Alania ...
The coarseness of sand is expressed by fineness modulus ( Mx ), defined as follows: (5.1) M x = A 2 + A 3 + A 4 + A 5 + A 6 − 5 A 1 100 − A 1. The bigger the fineness modulus is, the more coarse the sand is. The fineness modulus of the sand used in ordinary concrete is within 3.7 ~ 1.6.
fineness modulus of 6.23. 4.3.2. Quartz sand (fine aggregate): The quartz sand used in this investigation has a size range of 0.3-0.8mm.And its physical properties includes specific gravity of 2.65, bulk density of 1650 kg/m3, Fineness modulus of 2.2, with colour of greyish white and odourless.

(38.1-mm) -- 96 Concrete is made up of cement, fine aggregate (sand), coarse aggregate (stone sand based on the fineness modulus (IS 2386 - PART III 1963) as shown in. Jun 19, 2019 - Fineness modulus of ...
Quartz Sand; Grading of Sand. ... The fineness modulus sand should be between 2 and 3. A smaller value of fineness modulus indicates the presence of finer particles and vice versa. If good sand is not available in the nearby of the site, the substitutes may be used as fine aggregate.
In manufactured sand with well-designed screening system the general, the demand of natural river sand is quite high in required grading and fineness modulus (2.4 to 3.1) can be developing countries to satisfy the rapid infrastructure growth, achieved consistently .
Jun 01, 2014 As siliceous filler used quartz sand with a fineness modulus of 1.54. Si[O.sub.2] content was 92.4 wt. %. Raw material mixtures were prepared with 8 % of the active content of CaO. Loam content in the raw mix was varied from 5 to 70 wt. %. As a control, use lime -sand feed mixture. The rock added to the feed mixture in the form of lime- sand ...
Usually, coarse quartz sands with fineness modulus more than 2.5 are used as fine aggregate. The use of low fineness modulus sands, characterized by high intergranular porosity and high specific surface area, as a fine aggregate, leads to an increase in the concrete mixture …
Jul 31, 2016 Calculation of Fineness Modulus of Sand Let us say the dry weight of sample = 1000gm After sieve analysis the values appeared are tabulated below. Therefore, fineness modulus of aggregate = (cumulative % retained) / 100 = (275/100) = 2.75 Fineness modulus of fine aggregate is 2.75.
Dec 15, 2020 The Fineness Modulus is an index number that indicates the mean size of the sand particle. It is calculated by the sieve analysis test with standard IS sieves. The fineness modulus of sand ranges from 2.2 to 3.2. The formula for its calculation is, Fineness modulus of Sand = (Cumulative % retained) / 100.
Fineness Modulus of Sand. To calculate the fineness modulus of sand, the sum of the cumulative percentages retained on the following sieves are divided by 100: 150μm (No. 100), 300μm (No. 50), 600-μm (No. 30), 1.18mm (No. 16), 2.36mm (No. 8), and 4.75mm (No. 4) for fine aggregates.
Jul 12, 2021 Fineness Modulus of Fine Aggregate: The sand fineness module (fine aggregate) is an index number describing the mean size of sand particles. By doing sieve analysis with normal sieves, it is measured.. The accumulated percentage kept on each sieve is applied and the sum of the fine aggregate is subdivided by 100. To find the fine aggregate fineness modulus, we require 4.75mm, 2.36mm, …

4.2.1 Properties of Quartz sand Specific gravity = 2.45 Water absorption = 1.98% Fineness modulus = 4.2. 4.2.2 Properties of fine and coarse aggregate Specific gravity of fine aggregate = 2.5 Specific gravity of coarse aggregate = 2.6 Water absorption for fine aggregate = 1% Water absorption for coarse aggregate = 0.6%
Dec 01, 2000 The aggregate consists of 5–20 mm crushed rock, with the river quartz sand having the fineness modulus of 2.5. Four types of natural quartz sand are used for producing GQS with the Blaine specific area of 283–551 m 2 /kg, having SiO 2 content of 99%, 94.5%, 92.1%, and 84.7%, respectively.
