Concrete grade for the ribbon foundation: which is better to choose?

Without a quality and reliable foundation erectan equally high-quality and reliable construction is impossible. And the brand of concrete for the ribbon foundation is absolutely crucial in the characteristics of the future house.

It is concrete that holds the leading positions inconstruction, and the primacy has been steadily strengthened since the days of Ancient Rome. Using it, humanity has moved from the construction of temples and aqueducts (which are still in use) to the construction of runways and cosmodromes. It should be noted that in construction there is not only one brand of concrete used for the ribbon foundation: in special laboratories thousands of varieties of this wonderful material were created, each of which has a strictly defined purpose.

That is why before the start of construction first thingfind out not only the amount of material required, but also its type. The amount of concrete depends entirely on the type of foundation you have chosen. In particular, the grade of concrete for the strip foundation must be at least M200. Cement, sand and gravel are taken in strict ratio 1: 4: 4. Thus, per kilogram of cement will have four kilograms of fillers. In any case, do not allow any organic impurities to enter the finished mixture.

Regardless of which brand of concrete is used forThe foundation of the house is used, do not knead the mortar manually. In this case, it is virtually impossible to mix a quality solution, and the labor costs for it go unrealistically much. This statement is all the more fair, the cheaper it becomes to rent concrete mixers.

If you want to order already mixed upsolution, it should be indicated in advance not only what brand of concrete for the strip foundation you need, but also how much you need. You should know that you can not keep it for a long time. Of course, if you hired a team of builders, then for you such a decision will be made by their boss. But if you made a decision on an independent construction, you will have to solve this question, otherwise you will find yourself in front of a pile of unused concrete.

In case of self-manufacturingmortar must be remembered that its quality is significantly influenced not only by the cement used, but also by the filler. Rubble, gravel and sand should be ordered only from trusted suppliers, because otherwise you can expect an unpleasant surprise in the form of a heap of impurities that will have the most negative impact on the strength of the finished building.

If you accurately observe the ratio of allelements, the concrete will be durable, resistant to the effects of adverse environmental factors. Among other things, quality material will eventually become stronger with time. Note that the ideal composition from the first time can be prepared only by a professional builder, and you will not be prevented from doing a trial batch. Any brand of concrete under the ribbon foundation finally seizes after about 27-28 days.
