Bulking of sand depends on the moisture in the sand. But when the moisture is increased by adding more water, the particles of sand gets packed near each other as the film around the sand particles breaks and the bulking of sand is reduced. Dry sand and the send completely filled with water will have the exact volume.

2.4.2. Atterberg Limits. The Atterberg limits are a basic measure of the nature of a fine-grained soil.Depending on the water content of the soil, it may appear in four states: solid, semi-solid, plastic and liquid. In each state the consistency and behavior of a soil is different and thus so are its engineering properties.

aggregate and crusher sands are processed from a wide range of geological rock types, while our sands may be from natural sources such as pit or river sand, or may be produced by crushing and screening of aggregate material. As members of the Aggregate & Sand Producers Association of Southern Africa (ASPASA), our plants are subject to regular
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. The difference between the volume of loose soil to saturated soil is known as bulking of sand. During concreting process, we continually give vibrate concrete to reduce the pores ...
Particle size distribution: a poorly sorted material tends to exhibit a higher bulking factor. Bulking factor has been shown to be insensitive to the maximum particle size but is related to particle size distribution of a similar shape. Fine particles, such as those from the breaking of rock, reduce the bulking factor. Resultant particle shape ...

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 harsh behaviour while placing.
Bulking of Sand (%) = (h/H) x 100 = (2 / 10) x 100 = 20 %. Principle of Bulking of Sand . Bulking of a sand test depends on the fact that the dry volume of sand and saturated volume of sand has almost the same volume. Therefore in this test sand is filled in a container and water is added to it up to its saturation point.
Sand: The stowage factor for sand generally ranges between 1.3 to 1.5 m3/mt (45 to 50 ft3/lt), depending on the sand's moisture content, particle size, and compaction. Gravel: The stowage factor for gravel typically ranges from 1.4 to 1.7 m3/mt (48 to 60 ft3/lt), depending on the size, shape, and density of the gravel particles.
