Strengths & Grades
Our comprehensive range of concrete allows us to help our customers with projects of any type and size, from minor domestic works to major commercial applications. Different construction projects will require concrete of certain strength ratings, so understanding the difference between concrete grades is key to finding the ideal mix for your specific requirements.
At UCM Concrete, we supply a comprehensive range of concrete mixes across the Midlands Region. Below, we’ve highlighted just some of the different concrete grades we supply, alongside their strength ratings and their recommended uses.
Screed Mixes
What is screed mix ratio?
Screed mix ratio simply refers to the ratio of aggregate to cement needed to form screed. For finer screed, sharp sand is used, while more high-strength industrial mixes use a more coarse aggregate in the mixture.
Screed mix ratio can range between 1:3 – 1:5 cement to sand depending on the desired consistency and other factors.
However, the traditional standard screed mix ratio is 1:4 cement to sand, creating a soft, malleable texture that is easy to work with.
More ingredients can be added if the consistency is still not quite right. As a professional concrete supplier, we can take care of the mixing process for you.
Concrete Grading
We offer all different grades of concrete to cater for different requirements and applications. Our gradings range from C8 – a wet mix concrete used for kerb backing and bedding – and C10 concrete for drainage works to C40 concrete for structural usage and farming.
We also offer PAV 1 and 2 concrete grades, which include air-entrainment additives that help protect the surface from freeze-thaw problems.
We only utilise premium quality aggregates in every mix to guarantee that your graded concrete is suitable for the task at hand and will perform as expected. Use our helpful concrete calculator to calculate how much concrete you need.
