Which IS code gives the recommended guidelines for concrete mix design?
Try it first: pick an option, then read the explanation.
Correct answer: B. IS 10262
IS Code for Concrete Mix Design
IS 10262 is the Indian Standard that gives the recommended guidelines for concrete mix proportioning (mix design). It covers the method for selecting suitable ingredients and determining their relative proportions with the objective of producing concrete of the required strength, durability, and workability.
Other codes to know:
IS 456 → Code of practice for plain and reinforced concrete
IS 383 → Coarse and fine aggregate specification
IS 516 → Methods of testing strength of concrete
IS 800 → Code of practice for structural steel (not concrete)
IS 456 → Code of practice for plain and reinforced concrete
IS 383 → Coarse and fine aggregate specification
IS 516 → Methods of testing strength of concrete
IS 800 → Code of practice for structural steel (not concrete)
IS 10262 — option B.
Key takeaway
Mix design = IS 10262. Don’t confuse it with IS 456 (design of RCC structures) or IS 516 (testing).
