Q: Which IS code uses the recommended guidelines for concrete mix design?
  • A. IS 12813
  • B. IS 10262
  • C. IS 800
  • D. IS 1373
Correct Answer: Option B - Concrete Mix Design IS 10262 : 2009, means determination of the proportion of the concrete ingredients i.e. cement, water, fine aggregate, coarse aggregate which would produce concrete possessing specified properties such as workability, strength and durability with maximum overall economy. • The earlier IS code IS 10262 of 1982 for design of concrete mix has been revised in 2009 to IS-10262 : 2009 and is called "Guidelines for concrete mix proportioning". • IS 12813-Method of analysis of hydraulic cement by atomic absorption spectrophoto-meter. • IS-800-2007–Code for practice for general construction in steel.
