Workability of Concrete Workability of concrete is the property of freshly mixed concrete which determines the ease and homogeneity with which it can be mixed, placed, consolidated and finished’ as defined by ACI Standard 116R-90 (ACI 1990b). ASTM defines it ...
Factors affecting the workability of concrete are materials such as water content, cement concrete, sand and aggregate properties such as size, shape, grading, mix design ratio and use of admixtures.
Concrete slump and compacting factor tests are most used test for workability. The degree of workability of concrete depends on the values of test results.
To study the workability (determine the consistency) of prepared concrete either in the laboratory or laboratory or during the progress of work in the field and to check the uniformity of concrete from batch to batch.
Various tests for workability of concrete at construction sites i.e slump test, Vee-bee test, Compaction factor test and its recommended values are given.
