What is Aggregates | Aggregate Definition & its Types.

(3.) Types on the Basis of Density. Three types of aggregates are distinguished on the basis of their weight per unit volume. (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.

12/5/2014· Given the critical role that the interfacial transition plays in high-strength concrete, the mechanical properties of coarse aggregate will have a more pronounced effect than they would in conventional-strength concrete. Important parameters of coarse aggregate are shape, texture, grading


Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed

Density Of Concrete - How Much Does Concrete Weigh?

The density of lightweight concrete is 1920 kg per cubic meter or 116 lbs per cubic foot (3132 lbs per cubic yard). Lightweight concrete weighs less because it is made with an aggregate called pumice, a naturally light mineral. Density is simply a mass to volume

High-density polyethylene - Wikipedia

High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a thermoplastic polymer produced from the monomer ethylene. It is sometimes called "alkathene" or "polythene" when used for HDPE pipes.[1] With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, corrosion-resistant piping
