Terms of Concrete Constituents

Terms of Concrete Constituents

Three main constituents are actually enough to produce concrete:
·     Binder (Cement)
·     Aggregate
·     Water
 Due to continually increasing demands for the concrete quality (mainly durability) and huge advances in admixture and concrete technology, it is now possible to produce many different kinds of concrete.·     Standard concrete:               Concrete with a maximum particle diameter > 8mm Density (kiln dried) > 2000 kg/m³,maximum 2600kg/m³
·     Heavyweight concrete:        Density (kiln dried) > 2600 kg/m³
·     Lightweight concrete:          Density (kiln dried) > 800 kg/m³ and < 2000 kg/m³
·     Fresh concrete:                      Concrete, mixed, while it can still be worked and compacted
·     Hardened concrete:              Concrete when set, with measurable strength
·     Green concrete:                     Newly placed and compacted, stable, before the start of detectable setting (green concrete is a pre-casting industry term)
 Other terms in use are concrete, pumped concrete, craned concrete etc.
