Choosing the Right Type of Concrete
The planning stages of a construction project require attention to a whole lot of details, and the type of concrete being used is one that should be near the top of every list of priorities. But what type of concrete is best for your project? iMix Concrete will run through various types of concrete and the applications they’re best suited for.
Small wall footings, sheds and floors – C15
C15 is ideal for these kinds of projects. This particular type of concrete allows for non-permanent finishes to be placed on top, such as tiles, which means it is perfect for flooring. It is worth noting that it is only suitable for flooring without any embedded metal, such as steel rebar. Foundations and floor slabs – C20 For foundations for single storey buildings, internal floor slabs and oversites, you need C20 concrete. With a 28-day strength of 20 Newtons, it is strong enough to withstand the loads expected in these environments, without possessing the strength of other, heavy duty concretes.
Footings, foundations, groundwork and trench fill – C25
For this variety of applications, a versatile type of concrete is needed, and C25 fits that bill. Used in domestic and commercial applications alike, most commonly in foundations for houses and extensions, it is strong and durable, with a 25 Newton 28-day strength.
Driveways – PAV 1
Driveways are expected to withstand a high amount of wear and tear, as well as heavy loads on a regular basis. PAV 1 concrete is ideal for a driveway as it contains air-entrainment additives that create small bubbles, protecting the concrete from freeze-thaw damage.
Paths, patios and pavements – C30
With a 30 Newton 28-day strength, C30 is the recommended concrete for those looking to lay a patio or path in their garden , or for the laying of pavements. It can be used for garage bases, too – ‘external light use applications’ also fall into the category of suitable uses for C30 concrete.
Reinforced floors, walls and workshop bases – C35
Floors in certain environments are going to have to endure greater impacts than your average domestic flooring. Think of warehouses and other industrial environments – vehicles, machinery and materials make for a very heavy load, and as such the floor needs to be made of a heavy-duty concrete, such as C35.
