Bulk density, also called apparent density or volumetric density, is a property of powders, granules, and other "divided" solids, especially used in reference to mineral components (soil, gravel), chemical substances, (pharmaceutical) ingredients, foodstuff, or any other masses of corpuscular or particulate matter.It is defined as the mass of many particles of the material divided by the total
Apr 26, 2017 · Bulking factor is a ratio comparing the volume of a quantity of moist granular material to the volume of the same quantity when dry. There are many ways of classifying the soil in terms of it''s ease of excavation including seismic techniques. The most common in the United Kingdom at present however is the Ease of Digging scale
Topsoil is surface soil which is normally high in organic material and contaminated by residual grass seed and grass roots and reasonably free from subsoil, refuse, clay lumps and large stones. In most cases, topsoil is unsuitable for use as foundation material for bulk earthworks due to
Hence, a correction factor for bulking of sand has to be applied alterdetermining the rate of bulking for the sand to be used in mortar and concrete making. As regards the rate of bulking of sand, it has been observed that it is related to two factors. (i) percentage of moisture content in the sand. (ii) gramSize of the sand particles.
Feb 09, 2007 · I can''t imagine that the program''s help file doesn''t include rough numbers to use for these quantities based on the soil type. For cohesive soils, I would crudely estimate a shrink factor of 2030%, with the swell factor maybe 5% larger. You should ask a professional estimator or conduct data gathering over several projects to refine the

How to Calculate the Soil Compaction Factor By Jack Burton. SAVE Proper soil compaction ensures that things stay in place after they are built. Whether it''s an underground pipe, a sidewalk, a home, or a skyscraper, it all depends upon the soil being stable, and not moving due to water or further compression. Various machines compress soil, but
Oct 01, 2016 · Bulking of Sand. It can be defined as in increase in the bulk volume of the quantity of sand (i.e. fine aggregate) in a moist condition over the volume of the same quantity of dry or completely saturated sand. The ratio of the volume of moist sand due to the volume of sand when dry, is called bulking factor. Fine sands bulk more than coarse sand
Remember, the bulk factor will make the insitu volume larger, so it will be greater than 1. If you are given a bulk factor of 0.15, use 1.15 in the equation so that the soil becomes 15% larger. The shrink factor will make the insitu volume smaller, so it will be less than 1.
Sep 03, 2017 · The extent of sand bulking depends on the grading of sand. Finer Sand possesses more bulking than the medium and coarse sand. Thus, Bulking in the sand is high for fine sand and low for coarse sand. An increase of bulking in sand effects concrete mix and results in
Bulk density is commonly used when referring to solid mixtures like soil. Just like particle density, bulk density is also measured in mass per volume. Bulk density is useful for determining the density of a mixture that has many different compounds and elements in it.
''Bulking'' of excavated material. Enter the dimensions asked for and the estimator will provide the ''bulked'' up cubic metres of rock, chalk, earth, clay, sand and gravel. The calculations will be completed when you click calculate..
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.
Appliion of Shrinkage and Swelling Factors on State Highway Construction by Alexandria Rhea Crooks A thesis submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Master of Science Auburn, Alabama May 5, 2013 Keywords: Cut, earthwork, embankment, fill, shrink, swell
After reading this article you will learn about the bulk density of soils and factors affecting it. Bulk Density of Soils: Bulk density of soils is the weight of dry soil solid per unit volume of soil. This soil volume is the sum of the volume occupied by soil solids and volume occupied by air.
May 14, 2018 · This dataset is a characterisation of the soil and rocks and the potential bulking factor (likely excavated volume increases) at Formation (local to regional) level for Great Britain. The data is egorised into Class, characteristics of similar soils and rocks and Bulking Factor, range or ranges
Bulking of Sand. The increase in moisture of sand increases the volume of sand. 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.
As per the concrete expert''s opinion, bulking of sand is one of the critical factor which is responsible for the bad quality of concrete. Do you Know What is Bulking of Sand? Bulking of sand is the increase in the volume of sand due to the presence of moisture on the sand particles. The presence of moisture in aggregates cause the bulking of
Dec 13, 2008 · Day hit the nail on the head with knowing the material you are moving. 25% would be a very crude example and would work for sand to sandy lean clay. If you are in a real plastic clay 35% 40% wouldn''t be out of the question. I wouldn''t bid a plastic clay site with a 25% shrink factor, lucky for me this area is usually sand sandy lean clay.

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 film is formed around the particles, which causes
An example of this is sand: 100 cubic yards in place yields 111 cubic yards loose and only 95 cubic yards when compacted. Table 101 lists conversion factors for various types of soils. These factors should be used when you are preparing a table of cumulative yardage for a mass diagram.
Bulking factor is defined as: Bulking Factor = Volume after Excavation / Volume before Excavation. Similarly a shrinkage factor is defined for the compaction of a soil at it''s final destination.: Shrinkage Factor = Volume after Compaction / Volume before Excavation. Typical values can be
Inherent Factors Affecting Bulk Density and Available Water Capacity Inherent factors that affect bulk density such as soil texture cannot be changed. Bulk density is dependent on soil organic matter, soil texture, the density of soil mineral (sand, silt, and clay) and their packing arrangement. As
Soil Bulk Density as related to Soil Texture, Organic Matter Content also the most effective factor that affected the bulk density of soils. Index Terms soil bulk density, clay content, silt content, sand content, organic matter content, More details » Get Price
