Physical Properties of Mineral Aggregates | .Översätt den här sidan

An important property of aggregates is the internal pore characteristics. What make up this characteristic are the absorption, porosity and permeability of the aggregate. The size, number and continuity of the pores has an effect on its strength, its resistance to abrasion, texture of the surface, gravity, bonding capabilities as well as its resistance to freezing and thawing.

Aggregate (composite) - WikipediaÖversätt den här sidan

Aggregate is the component of a composite material that resists compressive stress and provides bulk to the composite material. For efficient filling, aggregate should be much smaller than the finished item, but have a wide variety of sizes. For example, the particles of stone used to make concrete typically include both sand and gravel
