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 C15 mix has a low cement content, meaning that the strength of the mix is one of the lowest of the design concrete mixes that we offer. This would be used when strength is not the main factor of your concrete application.
If the C15 concrete mix does not fit with your requirements, you can use our simple three step process to determine the concrete mix recommended for you. Or take a look at the wide range of concrete products we offer via our products page.
