MCK Mini-Mix Concrete Guide

concrete mixture

Ready-mix concrete is not just used for large scale commercial projects – it is a hugely useful material for domestic projects.

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
