Aggregates are generally thought of as inert filler within a concrete mix. But a closer look reveals the major role and influence aggregate plays in the properties of both fresh and hardened concrete. Changes in gradation, maximum size, unit weight, and moisture content can all alter the character and performance of your concrete mix.
Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or largesize gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soilcement, and in new concrete. After harvesting, aggregate is processed crushed, screened, and washed to obtain proper cleanliness and gradation.
Perception Well if you relate the strength of concrete with the size of aggregates only then it is not justifiable, because strength of cement concrete also depends upon watercement ratio. The concrete which is having more watercement ratio wi
For the same strength or workability, concrete with large size aggregate will require lesser quantity of cement than concrete with a smaller size aggregate. In a mass concrete work the use of larger size aggregate will be useful due to the lesser consumption of cement. This will also reduce the heat of hydration and the
Aggregate may be natural, manufactured or recycled. It includes gravel, crushed stone, sand, slag, recycled concrete and geosynthetic aggregates. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete.

Using aggregate makes concrete much stronger, with the aggregate acting as a type of reinforcement. The aggregate increases the lifetime of the concrete, and makes it more durable. Contractors can choose from fine aggregates, made from small particles of material, and coarse aggregates, which are made with large chunks.
Construction aggregate, or simply aggregate, is a broad category of coarse to mediumgrained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic are the most mined materials in the world. Aggregates are a component of composite materials such as concrete and asphalt concrete the aggregate serves as
Exposed aggregate concrete can almost be compared to a piece of granite or marble transformed by polishing A plain, unremarkable surface has been stripped away to reveal the exceptional beauty lying beneath. In the case of concrete, that beauty is in the form of decorative aggregate, either natural or manufactured.
A recent report by the National Ready Mixed Concrete Association reached the following conclusions 1. At a given water ratio, within the range employed in most structural concrete, smaller maximum sizes of aggregate will tend to produce higher concrete strengths than larger ones. 2. The larger sizes will require less mixing water and hence
The Effect of Aggregate Properties on Concrete Concrete is a mixture of cementious material, aggregate, and water. Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete.

The cement in a concrete slab usually holds the surface layer of aggregate in an exposed aggregate slab securely in place. Sometimes, though, this hold fails, and pieces of the aggregate break away. With the loss of the aggregate, the slab develops surface bald patches or depressions.
Size of aggregate depends mainly on three factors type of the structure, size of the structural member and nature of the work. Large sized aggregates have less total surface area hence less water is required to achieve good workability. Thus, you require less quantity of water to make a workable paste of cement mortar or concrete.
Aggregate is a term for any particulate material. It includes gravel, crushed stone, sand, slag, recycled concrete and geosynthetic aggregates. Aggregate may be natural, manufactured or recycled. Aggregates make up some 60 80 of the concrete mix. They provide compressive strength and bulk to concrete.
