A normal weight concrete weighs 2400 kg per cubic meter or 145 lbs per cubic foot (3915 lbs per cubic yard).The unit weight of concrete (density) varies depending on the amount and density of the aggregate, the amount of entrained air (and entrapped air), and the water and cement content.The density of concrete is a measure of its unit weight.Concrete is a mixture of cement, fine and coarse aggregates, water, and sometimes some supplementary materials like fly ash, slag, and various admixtures.

The first generation of SCC used in North America was characterized by the use of relatively high content of binder as well as high dosages of chemicals admixtures, usually superplasticizer to enhance flowability and stability.TY - JOURT1 - Rheological model for self-consolidating concrete AU - Bui, Van K. PY - 2002/11/1Y1 - 2002/11/1N2 - This paper presents the development of a rheological model for self-consolidating concrete (SCC).AB - This paper presents the development of a rheological model for self-consolidating concrete (SCC).As a result, pouring SCC is also much less labor-intensive compared to standard concrete mixes.Once poured, SCC is usually similar to standard concrete in terms of its setting and curing time (gaining strength), and strength.

SCC can be used for casting heavily reinforced sections, places where there can be no access to vibrators for compaction and in complex shapes of formwork which may otherwise be impossible to cast, giving a far superior surface than conventional concrete.
