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.
The bulk dry specific gravity of the fine aggregate (G sb) is used to calculate the void content. The effectiveness of these methods of determining void content and its relationship to particle shape and texture depend on the bulk specific gravity of the various size fractions being equal (or nearly so).
fine aggregate loosely in the mold, filling it until overflowing occurs, and heaping additional material above the top of the mold. Lightly tamp the fine aggregate into the mold with 25 light drops of the tamper. Each drop should start about 0.2 inch above the top surface of the fine aggregate.
Lightly tamp the fine aggregate into the mold with 25 light drops of the tamper (Figure 3). Each drop should start about 1/5 in. above the top surface of the fine aggregate. Remove loose sand from base and carefully lift the mold vertically. If surface moisture is still present, the fine aggregate will retain the molded shape. When the sand ...

Apr 26, 2020 The weights of the SSD coarse aggregates, fine aggregates and sand were measured by using balance. A flask was filled with(500 ml) of water in order to measure the weight of the submerged fine aggregate and sand by subtracting (weight of flask weight of (500ml) water) from (the flask weight 500ml of water weight involved sample weight).
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 subdivided by 100 gives the value of fine aggregate. To find the fineness modulus of fine ...
Fine aggregates flow freely into a 1 OO-mL copper cylinder. By knowing the bulk specific gravity of the fine aggregate, Gb and the weight of fine aggregate in the cylinder of known volume, the uncompacted void content can be calculated. Very angular fine aggregates will have high
The fine aggregate angularity (FAA) test (Figure 1) is an indirect method of assessing the angularity of fine aggregate. Fine aggregate angularity is important because an excess of rounded fine aggregate (often in the form of natural sand) can lead to HMA rutting. Figure 1 Fine aggregate angularity test.

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,
Dry aggregate contains 33 to 34% air voids, whereas sand contains 20% air voids and cement contains very fine particles hence it contains negligible are voids so we can ignore it. Now add the air voids of sand and aggregate that are 20% 34% 54% so this is the reason we have to add 54% for wet to dry volume of materials.
