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.SPECIFIC GRAVITY OF COARSE AGGREGATE AASHTO T 85,Diagram of Bulk SSD Specific Gravity C.

Bulking test on fine aggregates Bulking of fine aggregate or sand is the phenomenon of increase in sand volume due to the increase of moisture content. Bulking test on fine aggregates has to be performed before using it in construction.
This test (bulking of sand or bulking of fine aggregate) is to ensure that we are using the right amount of sand while concreting. What is Bulking of sand? Bulking of sand is nothing but the looseness of soil without compacting. Basically, water reduces the pores in the sand and compacts the soil.Bulking of Fine Aggregate YouTube,Aug 25, 2013· How to create a 3D Terrain with Google Maps and height maps in Photoshop 3D Map Generator Terrain Duration: 20:32.

Bulking is the increasing volume of fine aggregate in a loosely feel state, When it is moist due to present of moisture film around the partical there is no bulking. When the sand is dry or when it is fully saturated in with the water fine sand bulks more than coarse sand.BULKING OF FINE AGGREGATE YouTube,Apr 21, 2018· BULKING OF SAND: The volume of dry sand increases due to absorption of moisture. These volume increase of dry sand is known as bulking of sand. When dry sand comes in contact with moisture, a thin
Mar 04, 2011· The increase of volume of given weight of aggregates due to the presence of moisture is called bulking of aggregates. 5 to 8 percent of moisture of aggregate weight cause 20 to 30 percent volume increase. This because of the creation of thin film Properties Considered in Mix Design Superpave Mix Design,VMA is most affected by the fine aggregate fractions which pass the No. 200 sieve. The reason for this is that these particles tend to be absorbed by the binder film. Because they take up volume, there is a tendency to bulk (extend) the binder resulting in a lower VMA.
Jul 30, 2012· Loose Bulk Density. Loose bulk density can be determined by filling the container with dried aggregates until it overflows from the container. Now level the top surface of container by rolling a rod on it. After that, weight the aggregate mass that is inside the Bulking of Sand // Bulking of Fine Aggregate // YouTube,Aug 27, 2017· Bulking of Sand // Bulking of Fine Aggregate // Anime_Edu Civil Engineering Videos.

Jan 19, 2019· Bulkage or bulking of fine aggregate sand is nothing but the increase in the volume due to presence of water. When water is added or comes in contact with sand, first sand absorb it and then the water is coated on its surface which is termed as ad.SPECIFIC GRAVITY AND ABSORPTION OF FINE AGGREGATES ,1 SPECIFIC GRAVITY AND ABSORPTION OF FINE AGGREGATES AASHTO T 84 GLOSSARY Absorption: The increase in mass due to water 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
The increase in volume is known as “Bulking” The amount of Bulking increases initially with increase in water content but decrease to zero with further increase in water content over to bulking, Fine aggregate shows completely unrealistic volume. Therefore it is absolutely necessary that consideration must be given to the effect of bulking.BULKING OF FINE AGGREGATE WHAT, WHY & HOW?,Aug 02, 2017· Due to bulking, fine aggregate shows completely unrealistic volume. Therefore, it is absolutely necessary that consideration must be given to the effect of bulking in proportioning the concrete by volume. If care is not given to the effect of bulking, in the case of volume batching, the resulting concrete is likely to be undersanded and harsh.
The reason is that moisture causes film of water around sand particles which results in the increase of volume of sand. For a moisture content percentage of 5 to 8 there will be an increase in volume up to 20 to 40 percent depending upon sand. If the sand is more fine there will be more increase in volume. This is known as bulking of sand.Exp 5 Bulk Density Civil Engineers PK,This test method is used to determine the bulk density of the given fine grained specimen. During the concrete mix design, when the aggregate is to be batched by volume or by weight, then it becomes necessary to know the mass of the aggregates that will fill the container of unit 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.AGGREGATE BLENDING, ABSORPTION, & SPECIFIC GRAVITY,Aggregate Blending, Absorption & Specific Gravity 37 Batching M per sieve = %Ret * %Agg * M batch M per sieve = Mass of one aggregate in the blend for one sieve size %Ret = Percent retained on the sieve expressed in decimal form %Agg = The percent of the stock pile to being used in the blend in decimal form EXAMPLE:
The bulk density values determined based on this test can be used for many methods of selecting proportions for concrete mixtures. Added to that, the evaluation of the percentage of voids between particles in fine, coarse, or mixed aggregates is dependent on the bulk density.SPECIFIC GRAVITY AND ABSORPTION OF FINE AGGREGATE,aggregate. The specific gravity may be expressed as bulk oven dry (O.D.) specific gravity, bulk saturated surface dry (SSD) specific gravity, or apparent specific gravity. 1.2 The specific gravity and absorption of fine aggregate is normally determined on pass No. 4 material.
