It is impossible to build an equally high-quality and reliable building without a high-quality and reliable foundation. Moreover , the concrete brand for the strip foundation is absolutely crucial in the characteristics of the future home.
It is concrete that holds a leading position in construction, and this primacy is steadily strengthened since the time of Ancient Rome. Using it, humanity has moved from the construction of temples and aqueducts (which are still used today) to the construction of runways and spaceports. It should be noted that in construction far from one concrete brand is used for the strip 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 starting construction, the first thing they do is find out not only the amount of material required, but also its type. The amount of concrete completely depends on the type of foundation you have chosen. In particular, the concrete grade for the strip foundation must be at least M200. Cement, sand and gravel are taken in a strict ratio of 1: 4: 4. Thus, per kilogram of cement will have four kilograms of fillers. In no case should any organic impurities be allowed into the finished mixture.
Regardless of which brand of concrete for the foundation of the house is used, do not manually mix the
mortar . In this case, it is practically unrealistic to knead a high-quality solution, and it takes an unrealistic amount of labor to do it. This statement is all the more true, the cheaper it becomes to rent concrete mixers.
If you want to order an already mixed mortar, then you should specify 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 store 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 have made a decision on self-construction, you will have to solve this issue, otherwise you will be faced with a pile of unused concrete.
In the case of self-production of mortar, it must be remembered that not only the cement used, but also the filler has a significant influence on its quality. Crushed stone, gravel and sand should be ordered only from trusted suppliers, because otherwise you may expect an unpleasant surprise in the form of a bunch of impurities that will negatively affect the strength of the finished building.
If you precisely observe the ratio of all elements, then the concrete will be durable, resistant to the effects of adverse environmental factors. Among other things, a well-made material will become more and more durable over time. Please note that only the professional builder can prepare the ideal composition the first time, and it will not hurt you to make a trial batch. Any brand of concrete under the strip foundation finally sets in about 27-28 days.
