Are you looking for concrete for domestic or commercial purposes, or are you curious to know more about concrete classes and how you can use them? Worry no more because we are here to discuss various grades of concrete grades and their uses in this article.

Concrete grades and concrete mix grades are slightly different, don’t get confused. You will come to understand the difference in a minute.

So one would ask, what is a concrete mix grade?

Well, it is the minimum strength that concrete should have twenty-eight days after the construction is complete. Usually, the concrete grade or class is denoted by M as a prefix to the numerical value shows the strength the construction engineer desires. M stands for mix, and the strength is measured in MPa. For a concrete class of 20 MPa, strength will be denoted by M20.

Basic Knowledge About Classes of Concrete

It is essential to have a fundamental understating of the concrete classes so that you can ascertain exactly which one you need for your project.

The classes rank in ascending order of 5, beginning at 10. The classes provide the comprehensive strength for the mix following the 28 days after construction is over. Such that, C10 is interpreted to have 10 newtons strength, C15, C20, C30, have 15 newtons, 20 newtons, and 30 newtons strength, respectively.

Uses of the Concrete Classes

So, where and which is the best job at hand that you can use these concrete classes? Here is a list of some of the essential concrete grades and their best functional areas for construction.

Class	Recommended Uses
Class C15	This class of concrete comes in handy when you want to do floor blinding or build pavement kerbs. Its 15-newton strength is good enough to enable it to serve both your domestic and commercial construction purposes.
Class C20	It is another class of concretes that does well for constructing domestic floors and in putting up foundations. It is advisable to use this class where the structure is supposed to be lighter. C20 concrete is also suitable for constructing garages, driveways, workshop bases, and integrating your internal floor slabs. This type of concrete is strictly ideal for domestic purposes.
Class C25	These concretes are multi-purpose and can be used in all areas, both in domestic and commercial projects. You can always use the is used when doing foundations.
Class C30	Use these concretes when building roadways and pathways since it is the lowest concrete mix used for such projects. It is slightly more durable, weather-resistant, and can withstand heavily trafficked roads. It is purely for commercial purposes.
Class C35	It is a heavy concrete mix and is often suitable for building slabs, structural piling, and external walls. The concrete serves for commercial constructions.
Class C40	It is the most durable on this list. It can withstand harsh weather and chemical corrosion, making it the best choice for building septic tanks and farm structures. Use this concrete for commercial projects, establishing foundations, and creating beams. It can also be used on roads.
