What is the primary purpose of conducting a sieve analysis on aggregates?

Correct Answer: To determine the particle size distribution of aggregates.

Step 1: Understand what aggregates are. Aggregates are materials like sand, gravel, or crushed stone used in construction.
Step 2: Learn about sieve analysis. Sieve analysis is a test that separates aggregates into different size groups using a series of screens or sieves.
Step 3: Know why particle size distribution matters. The size of the aggregates affects the strength, durability, and workability of concrete.
Step 4: Realize the primary purpose. The main goal of sieve analysis is to find out how much of each size of aggregate is present, which helps in designing the right concrete mix.
