degree of workability is high when slump is?
> 100 mm
only a true slump is of any use in the test. a collapse slump will generally mean that the mix is too wet or that it is a high workability mix, for which the slump test is not appropriate. very dry mixes having slump 0 – 25 mm are typically used in road making, low workability mixes having slump 10 – 40 mm are typically used for foundations with light reinforcement, medium workability mixes with slump 50 – 90 mm, are typically used for normal reinforced concrete placed with vibration, high workability concrete with slump  100 mm is typically used where reinforcing has tight spacing, and/or the concrete has to flow a great distance.

section::::limitations of the slump test.









































the slump test is suitable for slumps of medium to low workability, slump in the range of 5 – 260 mm, the test fails to determine the difference in workability in stiff mixes which have zero slump, or for wet mixes that give a collapse slump. it is limited to concrete formed of aggregates of less than 38 mm (1.5 inch).









































section::::differences in standards.









































the slump test is referred to in several testing and building codes, with minor differences in the details of performing the test.
