Usually specified at design stage, this form of ready mix concrete is designed to comply with a compressive strength denoted by the class of mix. Mixes are measured in grades, with strengths ranging from 10 Newtons through to high strength concrete mixes available online at 45 Newtons. A C20 mix has a relatively low cement content, meaning that the strength of the mix is one the lower mixes of the design concrete products that we offer. This would be used when strength is not the main factor of your concrete application.
We offer an extensive range of concrete products, so if C20 doesn’t fulfil your needs take a look at the other mixes we offer, which includes everything from general mixes to reinforced mixes.
