Aggregates MCQ [Free PDF]
If aggregate remain on 4.75 mm sieve then they are called coarse aggregates. i.e. Coarse aggregate > 4,75 mm. If aggregates pass through 4.745 mm grade and retain on a 75-micron sieve then they are called fine aggregates. i.e. Fine aggregate 4.75 mm Note: For RCC work, the maximum size of aggregate is limited to …

All About Coarse Aggregate: Types & Properties
Coarse aggregate is a term used in construction to describe a type of material that is commonly used in the production of concrete. It is typically made up of various materials such as gravel, crushed stone, and recycled concrete. The size of the coarse aggregate can vary, but it is typically between 3/8 inch and 1.5 inches in diameter.
