It should be noted that what type of basement the owner of a country house would not choose, he will always have a question, what type of concrete should be chosen for this very foundation and how do the characteristics of concrete differ from each other.
Concrete of what brand is needed for foundation
Composition of concrete
Any concrete contains 3 basic components:
- Cement is a component that binds other fillers.
- Fillers - Crushed stone, gravel, sand, various loose additives.
- And directly water .
As a result of the synthesis of these groups of components, concrete is formed, it is worth noting that the quality of concrete directly depends on the percentage of cement in our fillers. Fillers are used to reduce the stress of concrete as a result of the solidification of the foundation, and in order to reduce the economic cost of the structure, since the cost of the building depends on the choice of concrete components.
Concrete marking
1. M - concrete brand.
2. B - class of concrete.
3. F - resistance of concrete to frost.
4. W - water resistance characteristic of concrete.
5. P - mobility of concrete.
Concrete grade
Concrete grade is a fundamental characteristic that shows us how a frozen foundation will transfer compressive loads after the process of solidification, that is, after 30 days.
Concrete M100 V7.5 - very low quality concrete is mainly used in preparatory work during construction for pouring concrete cushions under the foundation.
Concrete M150 B12.5 - concrete is not very good quality is mainly used in the construction of concrete paths and rough screeds.
Concrete M200 B15 - This concrete is used for the construction of elements with low loading such as stairs or for pouring tape base plates.
Concrete M300 B22.5 - The most popular brand of concrete in Russia, because the quality of this concrete can be assessed on a strict 4! .Applied for pouring the foundation and for the construction of good and quality country houses.
Concrete M350 B25 - quality concrete, which is used for the construction of concrete structures requiring extremely high strength.
Concrete M500 B40 - Rarely used in Russia, because concrete costs large investments are mainly used for the production of bank vaults or for the construction of special.objects.
Concrete grade
The class of concrete is denoted by the letter B and characterizes more detailed information about the degree of compression, information about more accurate data we can see above.
Mobility of concrete
Mobility of concrete Letter P - an indicator of which characterizes the fluid of a homogeneous concrete mixture and the coefficient of fluidity. It should be noted that even with a slight excess of water in this concrete can result in a loss of strength, and as a consequence, major problems.
Water permeability
Water permeability is the letter W. It characterizes the coefficient of water penetration of concrete by water, they usually range from 2 - the minimum value to 12 the maximum value. This factor should be taken into account if there are groundwater in your area and the foundation can "play" under flooding with underground underground sources, by the way, if you want to get rid of this problem, I recommend reading the article about the blind area around the house with your own hands and about the drainage systems that will leave your foundation inideal condition.
Resistance to frost
Resistance to frost letter F - the indicator of which characterizes how many defrosts and frosts are able to withstand concrete.
