The natural process of carbonation occurs in all concrete from the surface inward. In the process of crushing concrete to create recycled concrete aggregates, areas of the concrete that have not carbonated are exposed to atmospheric carbon dioxide. The LEED ® Green Building Rating System recognizes recycled concrete in its point system. Credit ...

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. Although aggregate is considered inert filler, it is a necessary component that defines the concrete's thermal and elastic properties and dimensional stability. Aggregate is classified as two different types, coarse and fine.

May 31, 2013· In practice, aggregates in stockpiles, plants, and in the mixture are rarely, if ever, at these moisture conditions. The absorption of the aggregate indicates the quantity of water which will be absorbed into the pore structure. Most commonly, aggregates will have a moisture content that is either below or above this absorption limit.

Every material has some specific gravity. The value is normally in digits like – 100. If the value is less than 1, then the material will float on water. If the value is greater than 1, then the material will sink. /cc means the cement is times heavier than the water of the same volume.

productivity levels in particular. Aggregate productivity gains come from improved selection and heightened competition that trade brings. A multitude of empirical studies have accompanied and been spurred by these theories (, Nina Pavcnik 2002, Andrew B. Bernard, J. Bradford Jensen, and Peter K. Schott 2006, and Eric A. Verhoogen 2008).
