The types of concrete and their benefits

A successful DIY or construction project depends on the strength and properties of the materials you use. Chances are, you will require a reliable supply of concrete during your project, and so you need to make sure you choose the best type of concrete for the job. 

In this article, we’ll take you through the types of concrete and their uses so you can make the best decision.

What are the types of concrete?

All concrete is mixed to offer different levels of strength and suit different applications. Let’s take a look at the main sorts of concrete available to you and their traits. 

Please note, the C placed at the front of each concrete number indicates the compressive strength of that concrete type. The higher the strength of the concrete, the higher the number it will have assigned to it. For example C10 indicates a compressive strength of 10 newtons. 

C10: A concrete mix commonly used in simple domestic or commercial projects, including patios and pathways. This material is not suitable for any structural jobs. 

C15: A mix best suited for kerbs and floor blindings. It can also be used for pathways and patios, too. 

C20: Commonly used in foundations over unstable ground, but only where the structure itself will be lighter than the concrete itself, meaning it’s often used for shed or garage bases as well as driveways. 

C25: This mix has multiple applications in domestic, commercial and agricultural settings, and is used for slab foundations and footings.

C30: At this level of strength, the concrete is tough enough for commercial uses and traffic areas such as work yards, farms or roadways. It’s a highly durable option and can resist weathering very successfully. 

C35: A strong, heavy-duty mix that is useful for areas with heavy traffic or places that require structural strength. As such, it’s commonly used in commercial applications and construction tasks like building bases, external walls, piling, and also for agricultural areas such as barns and pens.                                                                                                                                                   

C40: The strongest mix available, it’s almost exclusively used in commercial structural applications such as for support beams and foundations. Its incredible strength makes it the best placed for areas where chemical weathering would be present, such as near septic tanks or in agricultural settings, as it can withstand these conditions much better than weaker mixes.
