Question

If the mean sieve size is 8 mm, what size particles will be considered as flaky:

Having thickness less than 4.8 mm


Having thickness more than 4.8 mm


Having length more than 14.4 mm


Having length less than 14.4 mm​

Answer 1

Answer: Having thickness less than 4.8 mm

Explanation: flaky aggregate means it's least dimension is less 3/5 of its size.

3/5 ×8= 4.8 mm

If the aggregate size is 8 mm then all particles are less than of size 4.8 mm is a flaky particles.

Answer 2

Answer:

The particle that has less than 14.4 mm thickness will qualify as flaky.

Explanation:

• The surface, shape and texture of a particle Influencers the concrete that is freshly made.
• The particles that are elongated rough and angular need more water to make the mixture of concrete workable.
• In the given question  sieve is of 8 mm  thickness and to find the flaky aggregate the particle should have dimension less than three fifth of the dimension of sieve given and the particle that has less than 14.4 mm thickness will qualify as flaky.
