alleryStart learning →Per §10.7, the Indian Standard method of concrete mix design is described in:
AIS 456-1978 only
BIS 1199-1959 for fresh concrete tests
CIS 269-1989 for OPC grades
DIS 10262 specifically for mix design
Answer & Solution
Correct answer: D. IS 10262 specifically for mix design
1. §10.7 lists six mix-design methods: Trial-and-error, Fineness Modulus, Road Note No. 4, ACI method, British method, and the 'Mix design method as per IS 10262.'
2. IS 456 covers structural design, IS 269 the OPC grades and IS 1199 the fresh-concrete tests; only IS 10262 is the mix-design code.
