STANDARD
- IS: 2386 (Part 3)1963.
OBJECTIVE
- To determine the percentage bulking of sand.
APPARATUS
- Containers 2 nos.
- Steel scale.
PROCEDURE
- Place sufficient quantity of sand loosely in to a container until it is about two third full.
- Level the top of the sand and measure the height (h) of sand in the center with a steel scale.
- Empty the sand out of the container in to another container with out any loss.
- Fill the empty container half with the water.
- Put back about half of the sand in to the water and prod it with a steel rod about 6 mm in diameter so that its volume is reduced to a minimum.
- Add the reminder of the sand and prod it in the same way as described above.
- Smooth and level the top surface of inundated sand and measure its depth (h’) at the center.
CALCULATION
- Calculate the percentage bulking of sand from the equation given below
Percentage of bulking = ( (h/ h’)-1) x 100
REPORT
- Report the percentage bulking of sand to the nearest second decimal.
