At the point when the amount of water in sand turns out to be more than 20% or the sand is completely submerged in water its volume turns into the same as that of dry sand. The percentage of bulking of sand can be easily calculated by following this field method. 1. Pour the sample of damp sand in a graduated glass cylinder of 250 ml capacity. 2.

Calculating Bulking: Unveiling the Method. To determine the percentage of bulking, a simple yet effective method is employed: Take a container and fill 2/3 of it with sand. Measure the initial height of the sand (H1). Add water to the container, maintaining the same sand height. Allow the sand to settle. Measure the final height of the sand in ...

The amount of bulking of sand depends on the moisture content and particle size of the sand. It is seen that the higher the moisture content of sand having the greater the bulking of sand. Since, finer sands have more surface area per unit volume, therefore they show a greater degree of bulking than coarser sands.

limitations of bulking of sand: Improper bulking of sand can result in harsher concrete and less workability. Unmanaged bulking of sand can decrease the yield of concrete. It can affect water-cement ratio in concrete. If not meet the standard concrete mix proportion, it will hamper the strength and durability of concrete. Prevention of bulking ...

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.

River sand is dredged from river bed making it wet. Since river sand contains small size particles (which has greater surface area), it hold water for long, even when dispatched to site after days of dredging. ... Bulking of sand = V1 – V2 /V2.

This bulking of sand is dependent on two factors: 1. The fineness of sand particles. Fine sands, that is sand particles of size on close to 75 micron, show higher bulking as compared to the coarse sands. 2. Percentage moisture content present. We have already seen how water content affects the volume of sand.

Bulking of sand is defined as the increase in the volume of sand due to formation of a thin film of atmospheric moisture around sand particles. This layer generates a force between particles to move aside to each other.
