Three workability tests are incorporated in IS 1199–1959 for routine field measurement of fresh concrete. Which set of three tests is specified?
Answer & Solution
Correct answer: A.
1. IS 1199–1959 standardises three field-usable workability methods.
2. Slump cone covers the medium workability range and is simplest.
3. Compacting factor extends to high and very low workabilities.
4. Vee-Bee consistometer is best for low and very low workabilities.
5. Together the three cover the practical workability spectrum at site.
