As per IS 10262:2019, the standard normal consistency for M60 grade high strength concrete having a minimum 28-day cube compressive strength of 60 MPa is:
a) 30%b) 35%c) 40%d) 45% The standard specifies the normal consistency for concrete of grades M55, M60 and M65 as 30-35%, 30-40% and 30-45% respectively. As per Table 5 of IS 10262:2019, the nominal maximum size of aggregate assumed is 20 mm. The normal consistency is defined as the amount of water, expressed as a…
