Different Properties of Fresh Concrete for Construction Works
It is an indication of the fluidity or wetness of a mix and is measured by the slump test. Fresh concrete is placed in a metal cone. When the cone is removed, the concrete slumps a certain amount, depending on how fluid it is. A wet, soft mix slumps more than a drier, stiffer one. A high-slump concrete is one that is very fluid, and a low-slump ...
