Objective. For determination of specific gravity & water absorption of aggregates. Reference Standards. IS : 2386 (Part 3) – 1963 – Method of test for aggregates for concrete (Part I) Particle size and shape.

Exp 2 Aggregate Angularity Number. EXPERIMENT NO. 2 Determination of Angularity Number for the given aggregate sample. This test is also carried out for determining shape of the aggregates. Based upon shape the aggregates may be classified as Rounded, Angular or Flaky. Angular particles possess well defined edges formed at the intersection of ...

Flakiness index test is used to determine the particle shape of the course aggregate. The particle shape of the aggregates is obtained by the percentages of flaky and elongated particles accommodate in it. For base course and construction of cement concrete types, the presence of flaky and elongated particles are considered undesirable.

The shape of aggregate particles can significantly influence certain properties of concrete, both in its fresh and hardened states. Therefore, there is a need to be able to completely characterize the shape of aggregate particles, in three-dimensions, in order to develop computational models which accurately predict properties.
