Four concrete mix design trials were taken for the structures -Base slab, RCC walls and Roof slab Flowable Concrete M40 Grade for metro Station in UGC-07 of Mumbai Metro Project, Line -3. Satisfactory results obtained in trial mix no-TR 9. Coarse aggregate content, fine aggregate content and cementitious content were optimized, until a slump flow of 500-700 mm is achieved by slump flow test. For each trial, tests are carried out in order that the trial mix satisfies slump flow test, Flow table test and Sieve stability tests.
A. Test Methods
Flowable Concrete is able to flow under its own weight without segregation, bleeding with some vibration and these behavior of concrete can be ensured by tests like Flow table test ,Slump flow, Slump test , and Sieve stability tests of concrete to determine the flow ability, passing ability and segregation resistance of SCC mixtures according to BS: EN 12350 Part 2, 5,8, 9, 10, 11, and 12 [14]
