Feb 11, 2014· The volume increase of fine aggregate due to presence of moisture content is known as bulking. Fine sand bulks more as compared to coarse sand. Extremely fine sand particularly the manufactured fine aggregate bulks as much as about 40%. Note: Fine aggregate do not show any bulking when it is absolutely dry or completely saturated.

Bulking of sand is generally found in fine sand except for coarse sand. Objective: The standard test for bulking is dependent on the circumstance that when damp sand bulks, the volume of saturated sand rises. While applying fine aggregate (sand) to produce concrete, it is essential to find out the quantity of used sand that has been bulked.

2. Calculate the unit weight of the aggregate from the following formula: Unit weight per cubic foot = FA Where: F = Factor obtained in Section D A = Average net weight of aggregate required to fill the measure H. PRECAUTIONS Avoid segregation of coarse and fine aggregate by …
There are lots of methods and test, that we can use for assessing the quality of construction sand or Common sand. But when it comes to the case of site practices, the methods like bulk density, bulkage, specific gravity test etc, become difficult or up to an extent impossible. There comes the importance of Sieve test on fine aggregates.

The same value of fineness modulus may therefore be obtained from several different particle size distributions. In general, however, a smaller value indicates a finer aggregate. Fine aggregates range from a FM of 2.00 to 4.00, and coarse aggregates smaller than 38.1 mm range from 6.50 to 8.00.
The affected volume will be great for fine sand and will be less for coarse sand.If proper allowance is not made for the bulking of sand, the cost of concrete and mortar increases and it results into under-sanded mixes which are harsh and difficult for working and placing.
Nov 04, 2016· Objective: The standard test for bulking is dependent on the circumstance that when damp sand bulks, the volume of saturated sand rises.

It is difficult to measure surface water of the aggregate. Therefore its value may be assumed according to I.S. 456, 1964 given in Table 4.12. Property # 5. Bulking of Sand: The moisture present in fine aggregate causes increase in its volume, known as bulking of sand.
1 SPECIFIC GRAVITY OF COARSE AGGREGATE AASHTO T 85 GLOSSARY Absorption: The increase in weight due to water contained in the pores of the material. Bulk Specific Gravity (also known as Bulk Dry Specific Gravity): The ratio of the weight in air of a unit volume of aggregate at a stated temperature to the weight in air of an equal volume
aggregate size numbers. Fine aggregate or sand has only one range of particle sizes for general construction and highway work. The grading and grading limits are usually expressed as the percentage of material passing each sieve. Fig. 5-6 shows these limits for fine aggregate and for one size of coarse aggregate.

Overview. The fine aggregate specific gravity test (Figure 1) is used to calculate the specific gravity of a fine aggregate sample by determining the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. It is similar in nature to the coarse aggregate specific gravity test.. Figure 1: Fine aggregate specific gravity sample and pycnometer.
