The total volume of earthwork is the sum of the volumes of the prismoids formed by adjacent cross sections. When using the average end-area method, the prismoid is treated as a prism whose cross section is the mean of the two end areas of the prismoid. Equation 9.5.1A (1) presents the formula for use in the average end-area method.

Also the resulting concrete will be honeycombed and its yield will be reduced, raising its cost of production. The volume to be increased can be calculated either by knowing this percentage of bulking as shown above or by bulking factor. If, V m = vol. of moist sand . V s = vol. of saturated sand . then bulking = [(V m – V s)/V s]

Commonly-used bulking and compaction factor charts provide generic estimates, and don't necessarily reﬂect the actual state of the material being excavated. Incorrectly estimated or misunderstood factors can add signiﬁcant costs to a project due to …
4. CRUSHING RESISTANCE This test indicates the ease of processing (s trength) of the aggregate and the likelihood of attrition. Although materials which have a crushing resistance less than 130 kN cannot be classified as M/4 basecourse this does not necessarily preclude their use where stronger aggregates are not available.
Crushing Plant Design and Layout Considerations Ken Boyd, Manager, Material Handling, AMEC Mining & Metals, Vancouver, BC ABSTRACT In mining operations, the layout of crushing plants and ancillary equipment and structures is a crucial factor in meeting production requirements while keeping capital and operational costs to a minimum.
The amount of bulking of the crushed material for older equipment models has historically been approximately 20 percent of the crushing depth. These older crushing machines will generally crush to a larger particle size and coarser gradation. The result is a higher bulking factor and more excess material which must be removed.
Hence, a correction factor for the bulking of sand has to be applied after determining 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) gram-Size of the sand particles.
Soil or rock from the borrow expands when dropped on the lorry or the landfill - or stockpiled. One cubic from the borrow does not translate to one cubic dump. Bulking or swell factors for some materials: Material. Density at the Borrow. 103. (kg/m3) Bulking (Swell) Factor.
729 Bulking/Swell Factors for Various Excavated/Mined Materials The swell factor expressed in percentage is the amount of volume increase from bank volume (undisturbed, in place state) to loose volume (disturbed, excavated state) of the material due to voids (air pockets) added to the material after excavation.
Aggregates are used in concrete to provide economy in the cost of concrete. Aggregates act as filler only. ... The ratio of the volume of moist sand due to the volume of sand when dry, is called bulking factor. ... The aggregate crushing strength value is a useful factor to know the behavior of aggregates when subjected to compressive loads.
Swell and shrinkage factors in construction can be used to estimate the volume of excavated material as in changes from in place to excavated and from in place to compacted state. There are three terms associated with this: Bank volume (volume before excavation, material in …
· The bulking factor of rocks reflects the bulking property of rocks and is equal to the ratio of the volume of loose crushed rocks to that of intact rocks before being damaged. 27 Therefore, as shown in Figure 4, the bulking factor k of broken coal and rock masses during the whole compaction test can be calculated as follows ...
12.3 Buckling Load Factor The buckling load factor (BLF) is an indicator of the factor of safety against buckling or the ratio of the buckling loads to the currently applied loads. Table 12‐1 Interpretation of the Buckling Load Factor (BLF) illustrates the
The quality of concrete used for concrete making affect the grade of concrete. Aggregate must be strong and hard enough to resist the crushing action. They should not have cover of organic materials, clay, and dust otherwise it will affect the bonding strength of concrete and aggregate. The aggregates used for concrete must be durable.
An excessive amount of moisture can reduce the strength of concrete. If proper management of bulking of sand for concrete is not done then it may result in under sanded mixes can be harsh and make it difficult for working and placing. Factor affecting the bulk density: Particle size:
STRENGTH 10% Fines Aggregate Crushing Value (10% fact), determined in accordance with TMH1 method B2, shall be not less than the appropriate value in table 3602/2, column 3. The Aggregate crushed value(ACV), determined in accordance with TMH1 method B1, shall not exceed the appropriate value in the 3602/3.

The bulking factor is the ratio or percentage of the volume change of excavated material to the volume of the original in situ volume before excavation. The bulking factor is used to estimate the likely excavated volumes that will need to be stored on site or perhaps removed from site. The bulking factor can be used to help mange the footprint ...
CCA named REPA19 was obtained by removing particles larger than 19 mm from the original CCA (REPA37.5 with D max =of 37.5 mm) provided from a concrete crushing plant (Photo 1a). REPA stands for "recycled electronic pole aggregate". Photo 1b shows some particles of REPA37.5 after removing the surface mortar layers with hydrochloric acid.The original …
This will cause, less quantity of concrete per bag of cement. For example, if the bulking of sand is 10% and if mix ratio is 1:2:4, the actual volume of sand used will be 1.1 × 2 =2.2 instead of 2 per unit volume of cement. If this correction is not applied the actual dry sand in the concrete will be, instead of 2 per unit volume of cement.

Assume you are using dry gravel with a swell percentage of 15% and a shrink percentage of -7%. Plug those values into the calculator and it will tell you that the compaction factor = 1.237. Multiply the 1185 cubic yards by 1.237. 1185 * 1.237 = 1465.9. To complete this job you will need 1465.9 cubic yards of this gravel in loose state volume.

For instance, a bulking factor for Clay and Gravel is typically 1.15. If your excavation was 15 m3. Your volume size would be 1.15 x 15 = 17.25 m3. You must consider the bulking factor of the material you are digging to ensure you correctly plan for the removal costs and time to do it in.
