Workability of concrete can be measured by which of the following tests?
Building MaterialsBuilding MaterialsEASY
Choose the correct answer
A
Cube crushing test
B
Slump test, compaction factor test, Vee-Bee test — all measure workability
C
Impact value test
D
Soundness test
Correct Answer
B. Slump test, compaction factor test, Vee-Bee test — all measure workability
Why is this the answer?
Workability tests: (1) Slump test (IS 1199) — most common, measures consistency; (2) Compaction factor test — better for low workability mixes; (3) Vee-Bee consistometer — for very dry mixes; (4) Flow table test — for superplasticised concrete. Slump range: 0–175 mm; Compaction factor: 0.7–0.95.
