TESTS ON aggregate

Bulk Density (Fine Aggregate)

Code: This test is done as per IS: 2386 (part 3): 1963.

Procedure:

• i) Take the weight of empty measure (W).
• ii) Fill the measure with aggregates sample for about one third height and tam evenly with 25 strokes of the rounded end of the tamping rod.
• iii) Add a similar quantity of aggregate as second layer and tamp it evenly with 25 strokes.
• iv) Fill the measure with a third layer of aggregate up to over following and tamp it with 25 strokes.
• v) Strike off the surplus aggregate using the tamping rod as a straight edge.
• vi) Take the weight (w1).
• vii) Empty the measure and fill it again to over flowing by means of a shovel, the aggregate being discharged from a height not exceeding 5 cm above the top of the measure.
• viii) Level the surface of the measure and weight it (w2).

Uses:

The experiment should be done for coarse and fine aggregates.
