Resistances of concrete

Concrete is a material that has become unavoidable over time mainly because of its high compressive strength. It is this important resistance that allows us today to build concrete buildings and use this material to withstand enormous constraints. Concrete is a generic name, but beneath it is a palette of materials that you can build with. Concrete subassemblies each have very specific characteristics, especially in terms of resistance, and this is something you will need to pay attention to before starting construction. In general, there are three types of stress that your concrete can be subjected to, compression (like loaded beams for example), traction (such as hangers) and bending (like beams). The type of stress to which the reinforced concrete element will be subjected will therefore be decisive for the strength of the concrete to be chosen.If you want the Ready Mix Concrete in Lahore or you are looking for any building solutions, then Ittefaq Group is here to serve you.
Compression
Concrete alone is a material that is naturally resistant to compression, especially if it is reinforced, so it is under this type of load that it will be tried to subject it to maximum rather than to traction. It is for this reason that the concrete is very rarely used alone, but that it is more often armed with bars steel which, they, will take again the efforts of traction. Whatever concrete you choose, it will be particularly suitable for building elements subject to compression.
The concrete strength class gives us its compressive strength directly, in fact the strength class of the concrete is denoted CX / Y where X represents the 28-day strength of a cylindrical concrete specimen while Y represents the resistance to 28 days of a rectangular test tube. These normed values will therefore be most useful to choose your concrete according to the loads it will have to support. The concretes conventionally used on construction sites or for your house are C25 / 30 or C30 / 37 whereas the higher resistance classes are reserved for constructions of much larger size.For more:www.ittefaqgroup.pk/
