Difference Between Fine and Coarse Aggregate - Civil ...
Fine Aggregate vs Coarse Aggregate. Fine and coarse aggregates have some major differences. Sources of main differences between deep and shallow footings are definition, size of particles, materials, sources, surface area, function in concrete, uses, etc. In the following table the main differences between Fine and coarse aggregate are given:
Specific Gravity of Fine Aggregate-Test on Aggregates
Fine aggregate is used in many fields in sites for many purposes.So the determination of specific gravity of fine aggregate is very essential. Specific gravity of fine aggregate can be defined as the ratio of the weight of given volume of coarse aggregate to the weight of given volume of distilled water.

As per the definition given in the ‘IS: 2386 (Part III) – 1963’, (Indian Standard- Methods of Test for Aggregates for Concrete – Specific Gravity, Density, Voids, Absorption and Bulking), the specific gravity of coarse aggregates is the weight of the aggregates dried to constant weight in an oven at 100°C divided by its absolute volume including the natural voids within the aggregate ...
A Detailed Guide on Grading of Aggregates.
Grading of aggregates is aimed at determining the mean size of the particle in a given batch of aggregates. This is commonly found by the Method of Fineness Modulus. The method can be used to determine fineness modulus of coarse aggregates, fine aggregates, and all-in aggregates, i.e., mixed aggregates.
What is Fineness Modulus of Coarse Aggregates and Its ...
Fineness modulus of coarse aggregates represents the average size of the particles in the coarse aggregate by an index number. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fine aggregate.

Water, at a temperature of 73.4°F (23°C) has a specific gravity of 1. ... aggregate into the towel and then shaking and rolling the aggregate …
Aggregates - Types of Aggregates | Coarse Aggregate, Fine ...
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. Those particles that are predominantly retained on the 4.75 mm (No. 4) sieve, are called coarse aggregates.
Aggregates for Concrete
blast-furnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the pit or plant. Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected. Close to half of the coarse aggregates used in portland cement concrete in North America are gravels;
Classification of Aggregates as per Size and Shape -Coarse ...
Classification of aggregates based on shape and size such as coarse and fine aggregates are discussed here, What is an Aggregate? Aggregates are the important constituents of the concrete which give body to the concrete and also reduce shrinkage.
