What is Aggregates Aggregate Definition its Types.

(i) Standard or Normal: These types of aggregates give strength and weighting to the Concrete of around 2300 to 2500 kg/m 3. Gravels, Sand and Crushed stone, are all classed as Standard or Normal Aggregates. (ii) High-Density Aggregates: These are that type of Aggregates, which is used in standard proportions yield in heavy weight concretes.

What are high-density aggregates?

A. High-density aggregates generally consist of high-density minerals or rocks, or they consist of man-made materials, such as steel or iron. High-density aggregates are used to produce concrete that has higher than normal density, usually for radiation shielding or an application where high-density concrete is needed for counter balancing, ballasting, or stabilizing.

7 Lab Tests on Aggregates to Make Better Concrete for ...

Aggregates are subjected to the physical and chemical action of rain-water, groundwater and the other impurities of the atmosphere. This can lead to a change in the volume which is not good and substandard for the durability of construction. The property of aggregates to withstand the adverse action of weather is known as soundness of aggregate.
