What is meant by fine aggregate?

Fine aggregates are essentially any natural sand particles won from the land through the mining process. Fine aggregates consist of natural sand or any crushed stone particles that are ¼” or smaller. Frequently referred to as washed concrete sand or manufactured sand, C33 refers to the grading or size of the material.

What are the uses of fine aggregate?

Fine aggregate is used in making thin concrete slabs or other structural members and where a smooth surface is desired; coarse aggregate is used for more massive members.

What is fine coarse aggregate?

Fine aggregates generally consist of natural sand or crushed stone with most particles passing through a 3/8-inch sieve. Coarse aggregates are any particles greater than 0.19 inch, but generally range between 3/8 and 1.5 inches in diameter.

How do fine aggregates afeect concrete mix design?

How Fine Aggregate Affects Mix Design of Concrete? Fineness Modulus. It is one of the factors that influence concrete mix design since it controls the proportion of sand in concrete mixture. Moisture Content. Moisture content of fine aggregate is a crucial factor while suitable water to cementitious material ratio are established. Specific Gravity. Silt Content.

What is type an aggregate?

Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar. Types of aggregates include Coarse aggregate and fine aggregate.
