Unformatted text preview: American University of Sharjah College of Engineering Department of Civil Engineering Instructor: Arshi Faridi E-mail : [email protected] Course: CVE 202 Experiment #: 7B Concrete Flow Purpose: To determine the flow of concrete of high to very high workability, according to BS 1881: Part 105: 1984. Background: Since the long-term properties of hardened concrete: strength, volume stability, and durability are seriously affected by its degree of compaction, it is vital that the workability of the fresh concrete be such that the concrete can be properly compacted. The strict definition of workability is the amount of useful internal work necessary to produce full compaction. Unfortunately, there is not acceptable test, which will measure directly the workability as defined earlier. However, other tests (Table 1) are used widely to give a measure of workability. One of these tests is the flow test....
