This form of ready mix concrete is typically specified during the design stage.

Each of our mixes is designed in compliance 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 pre square millimeter.

For example a C25/30 is required to reach a compressive strength of 30 newtons after twenty eight days. The strengths of a mix can range from 10 newtons through to high strength concrete mixes at 50 newtons.
