Concrete slump test is a measurement of concretes workability, or fluidity. its an indirect measurement of concrete consistency or stiffness. a slump test is a method used to determine the consistency of concrete. the consistency, or stiffness, indicates how much water has been used in the mix. the stiffness of the concrete mix should be matched to the requirements for the finished product quality
The slump test result is a measure of the behavior of a compacted inverted cone of concrete under the action of gravity. it measures the consistency or the wetness of concrete which then gives an idea about the workability condition of concrete mix.
In order to reduce the influence on slump of the variation in the surface friction, the inside of the mould and its base should be moistened at the beginning of every test, and prior to lifting of the mould the area immediately around the base of the cone should be cleaned from concrete which may have dropped accidentally.
The slumped concrete takes various shapes, and according to the profile of slumped concrete, the slump is termed as
In a collapse slump the concrete collapses completely. a collapse slump will generally mean that the mix is too wet or that it is a high workability mix, for which slump test is not appropriate. it means the water-cement ratio is too high, i.e. concrete mix is too wet or it is a high workability mix, for which a slump test is not appropriate.
In a shear slump the top portion of the concrete shears off and slips sideways. or
If one-half of the cone slides down an inclined plane, the slump is said to be a shear slump. the shear slump indicates that the result is incomplete, and concrete needs to be retested for valid results.
In a true slump the concrete simply subsides, keeping more or less to shape
The concrete slump test is known as quotstandard test method for slump of hydraulic-cement concretequot and carries the code astm c 143 or aashto t 119. united kingdom amp europe in the united kingdom, the standards specify a slump cone height of 300-mm, a bottom diameter of 200-mm and a top diameter of 100-mm.
