There are different brands of concrete.The proportions of the concrete mixture before cooking is certainly worth exploring.In order to get quality solution, it is necessary to comply with the technology of mixing, as well as to monitor the composition.
comparing different brands of concrete
concrete composition will depend on whether the appointment should have a future construction.Thus, for solution M100 minimal amount of cement is required than in the manufacture of M450.This is due to the high cost of raw materials, if you compare it with sand and gravel.The composition of M100 should be the same amount of cement in the concrete M450.This is due to the fact that these compounds are used for different purposes.For example, M450 is able to undergo much more impressive as compared with the load M100.
proportions for different grades of concrete
As a rule, a trade solution was produced using cement M400 and M500.Furthermore, the mixture contains gravel, sand, and in some cases various additives, including antifreeze.In order to prepare concrete of different brands, it is necessary to take different ratios of ingredients.If the work requires the use of concrete to the presence in its composition of cement brand M400, it will use a ratio of cement, sand and gravel in the following proportions: 1: 4.6: 7.At the same time be able to get concrete grade M100.
In order to prepare a mixture of cement using a M150 with the same brand, it is necessary to use materials in the same sequence with the following proportions: 1: 3.5: 5.7.To prepare the solution M200 ingredients must be taken in the ratio 1: 2.8: 4.8.For certain brands of concrete proportions of the concrete should be well understood before work.Thus, in order to prepare a solution marks M250 need to connect the components using the proportion in which the first ingredient should be used in an amount of one part, the second - in the amount of 2.1, and the third - 3.9.Concrete (grade 300) is obtained at a ratio of 1: 1.9: 3.7.To prepare the composition of the brand M200 is necessary to mix the ingredients in the ratio 1: 2.8: 4.8.In order to obtain a mixture marks M250 need to connect the components using the proportion in which should be one of the first component, 2.1 and 3.9 of the second - third.Product brand M300 prepared using a ratio of 1: 1.9: 3.7.
To make certain brand of concrete proportions of concrete can be used those described in the article.In order to obtain a solution, which will have a mark M400 need to connect the components in the proportions 1: 1.2: 2.Product brand M450 formed by using the basic components in the ratio 1: 1.1: 2.5.
proportions for concrete with cement M500
can be used when mixing with cement M500 solution, then the same components are connected in a different proportion.Thus, for the preparation of M100 will be necessary to mix the cement and aggregate in the form of sand and gravel specially prepared in the proportion 1: 5.8: 8.1.For the process solution works M150 need to add ingredients to the mixer in a ratio of 1: 4.5: 6.6.If mixing with use of a ratio of 1: 3.5: 5.6, you get the M200.Concrete M250 will be able to obtain, if you add all the ingredients in a ratio which is as follows - 1: 2.6: 4.5.
For in the course of construction works of a certain brand of concrete proportions of concrete must be observed.This will produce a mixture with the desired quality characteristics.Concrete grade M300 obtained by using a ratio of 1: 2.4: 4.3.M400 is obtained by applying a ratio of 1: 1.6: 3.2.The solution will be able to shut the M450, will be used when the scheme is 1: 1.4: 2.9.
specifications mixture
Builders know what cement is used in the preparation of one or another variety of concrete.This is determined by the types of work that are expected to produce.The higher the quality of cement, the less of it will be necessary to obtain a solution.Brand material determines the compressive strength, but this value can be set only after making acquire resistance, and it usually takes 28 days.In the construction of the most common mixture that is determined by marks from 50 to 550.
Scope
brands of concrete and their characteristics presented in this article will help you make the right choice for high-quality design.Technology of preparation of the solution and its proportions are determined by the type of work, as well as the purpose of the object.M100, for example, has found its application by pouring the foundation of the belt type and monolithic plate.This mixture must be applied in a thickness ranging from 5 to 10 cm. Quite often, such a composition is used during road construction, moreover, it is indispensable in preparing the stacking base coat.If a comparison of this mixture with M150, it is possible to say that the latter option is perfect for floor screed, fill the sidewalk and the belt manufacturing base.
table concrete often helps beginners to masters.M200 solution can be applied not only in private, but in the construction industry.Most often it is used in the construction of low-rise houses, pouring of concrete blocks and road plates.While the M250 has a more impressive strength, it is not as claimed in the particular construction.It is usually used in the pouring of stairs, pavings, foundations, strong fences, as well as the construction of a monolithic foundation.
Concrete (grade 300) is most common in the regeneration of roads, pavings and floors, as well as filling the sidewalks.The same can be said about the brand 350. Such mixtures can be called universal.M400 can be used for arranging all kinds of constructions of any purpose.Poured through this concrete structure require special operating conditions.It is worth mentioning the M500, it is indispensable in the construction of dikes, dams and facilities that need to be of high strength.
About
as cement in the construction of foundations in the construction of most commonly used concrete M200-M500.It is worth remembering that not only the correct mixing and application of true proportions are the key to obtain a solution of sufficiently high quality.If you use the cement that had been stored for a long time or wrong, high humidity, the quality of the mixture is not the best, even if the brand of cement is high.This indicates that the raw materials required to be stored in a dry place and be used in its recommended as soon as possible after purchase.
price solution
If you choose to use in the construction of concrete, brand, price and quality of which will be different, be sure to review the main characteristics of this building material.Let's talk a little bit about the financial part of the issue.Concrete grade M100 will cost 2100 rubles.Whereas the price of the M150 is slightly higher than this figure - 2250 rubles.For concrete M300 will have to pay 2800 rubles.
In conclusion
It is worth noting that the brand of concrete - enough important component in the process of construction or repair work.It is from this will depend on the characteristics of the structural strength after curing, the duration of life of the monolith, water resistance and quality that determine resistance to low temperatures.Mark defines indicators that characterize the compressive strength.This characteristic is determined in kilograms.
If you want to build a structure with a more impressive quality characteristics, it is necessary to use concrete with a higher compressive strength.However, the same structure can be obtained if use different types of cement.Do not assume that using the more expensive material does not get saved.On the contrary, if we use higher quality cement, then during the mixing of the solution it need far less than that which has not so high quality and can not provide the desired viscosity.Once you have studied the grade of concrete and its characteristics, you can begin to work.
