Slump test and compaction factor test

Webb11 sep. 2024 · Compaction factor test. In this test the amount of compaction obtained by spending a known amount of energy is measured. This gives an idea of workability. The apparatus (Fig. 8.3.) used for the test consists of two hoppers A and B and a cylinder C. The hoppers are provided with hinged bottoms. WebbWorkability means how easily the concrete can be mixed, handled, transported, placed in position, and compacted. There are two other tests used to measure the workability of concrete; Compaction factor test and Vee-Bee test. Slump test is also known as slump cone test as a cone is used in the test.

WebbThe compacting factor gives the behavior of fresh concrete under the action of external forces. It measures the comparability of fresh concrete which is an important aspect of workability, by measuring the amount of compaction achieved for given amount of work. The compacting factor test has been held to be more accurate results than slump test. Webb8 juli 2024 · The degree of compaction, called the compacting factor, is measured by the density ratio, i.e. the ratio of the density actually achieved in the test to the density of the same concrete fully compacted. The test, known as the compacting factor test, is described in BS 1881-103 : 1993 and in ACI 211.3-75 and is appropriate for concrete with …

Webb3 mars 2024 · The slump test is a measure of consistency or the wetness of the concrete mix. It is suitable for field applications, suitable for concrete of high and medium workability. Slumps for various types of concrete is measured in mm. 2) Compacting factor test: It is more accurate than a slump test. WebbThe slump check is a realistic way to gauge the workability. The concrete slump test and compaction factor test are used to determine the consistency of fresh concrete before it sets.
