.: using the British Method, design a Concrete mix for a blinding with a specified characteristic
strength (fcu) = 17.5 N/mm2 (MPa) at 28 days by considering the following:
Maximum aggregate size 20 mm
Aggregate type:
Crushed coarse aggregates
Uncrushed fine aggregate
Cement type: Rapid Hardening
Required slump = 30 – 60 mm
The fine aggregate falls in zone 2
Assume zone B for figure 1
Assume K = 2.33
Relative density of combined aggregates is 2.5
NB: Do not Adjust the amount of water in the mix design
