This type of concrete mix is used in a broad range of applications such as kerb backing, slab work etc. A Standard Mix (ST) has set cement contents as defined in BS 8500-2 but with no guaranteed design strength. It consists of cement, water, stone and graded sand. An ST4 is one of the wettest of our ST mixes, meaning that the consistency of the mix is extremely fluid, and the strength is therefore reduced, but still retaining a set cement content. This would be used when fluidity is the main factor in your application.
