There are different grades of concrete depending on what / how it is being used – We have put together a quick guide for some of the domestic jobs you might be working on along with a some notes on understanding what everything means!
C = cylindrical value
Second Number is always strength class ie C32/40 = 40N Concrete
D= aggregate size eg: D10 = 10mm aggregate D20 = 20mm aggregate
S = Slump – This is how wet the concrete is (Lower value = Drier)
Note– If using a Concrete Pump, at a minimum you will require S3 Pump mix concrete between 100-150mm slump
