concrete | Definition, Composition, Uses, & Facts .

Concrete is characterized by the type of aggregate or cement used, by the specific qualities it manifests, or by the methods used to produce it. In ordinary structural concrete, the character of the concrete is largely determined by a water-to-cement ratio. The lower the water content, all else being equal, the stronger the concrete. The mixture must have just enough water to ensure that each ...

Grading of Aggregates in Concrete Spreadsheet .

The grading of aggregates in concrete is usually measured using a sieve analysis which uses a series of sieves to capture and separate aggregates of different sizes, allowing the aggregate distribution to be measured. The sampling and testing of aggregate gradations is completed in accordance with BS EN 932 and BS EN 933.

Concrete - Wikipedia

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past limebased cement binders were often used, such as lime putty, but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (named for its visual ...

Function and Importance of Aggregate in Concrete

• Coarse aggregate is used to describe particles larger than 4.75 mm, and the term fine aggregate is used for particles smaller than 4.75mm; typically, fine aggregates contain particles in the size range 75 µm to 4.75 mm, and coarse aggregates from 4.75 to about 50 mm, except for mass concrete which may contain particles up to 150 mm. • Most natural mineral aggregates, such as sand and ...
