WebbToo wet mix shows collapsible nature of slump. Compacting factor test This test is generally carried out in laboratory but can be used in site also. It is particularly useful for concrete mixes of very low workability (or very dry concrete) as they are insensitive to … WebbDiscussion and Conclusion. Compaction factor normally falls between the range of 0.8 – 0.92. This test gives more accurate results than slump test while dealing with relatively dryer concrete mixes. Compaction factor test gives more precise and sensitive results. Compaction factor of 0.75 to 0.80 are used for concreting of shallow sections ...
Slump test and compacting factor tests are the most widely used workability tests for concrete. The degree of workability of concrete depends on the values of test results obtained from slump test and compacting factor tests. There are many types of concrete construction, and each type has different workability requirements. Webb6 maj 2016 · Hence the compaction factor test is used. • The compaction factor test gives the behavior of fresh concrete under the action of external force. • In this test, the compaction achieved through a free fall of concrete determines its workability. 5.
