This form of ready mix concrete is usually specified at design stage.
Each mix is designed to comply with a compressive strength denoted by the class of mix, which is quality assured to meet British/European standards, BS 8500-2.
Mixes are measured in grades which are calculated in newtons per square millimeter. For example a C25/30 is required to reach a compressive strength of 30 newtons after twenty eight days. Strengths can range from 10 newtons through to high strength concrete mixes at 50 newtons.
C35 concrete mix uses
C35 is a very strong concrete mix and it's recommended use is on industrial floors, reinforced foundations, piling and underpinning. If you are unsure how much concrete mix your project requires, take a look at our concrete calculator.
