The grade of concrete, proportions of concrete. The use of concrete

There are different grade of concrete. The proportions of the concrete before the mix is certainly worth exploring. In order to obtain a high quality solution, you need to follow the technology of mixing, and to follow the composition.

Comparing concretes of different brands

The composition of the concrete will depend on what the purpose of a future design. So, to prepare the solution M100 requires less amount of cement than in the manufacture of M450. This is due to the high cost of raw materials, when compared with sand and gravel. In the composition of the M100 should not be the same amount of cement as in concrete M450. This is due to the fact that these formulations are used for different purposes. For example, the M450 is able to undergo a much more impressive load compared to the M100.

The Proportions for different grades of concrete

As a rule, the commercial solution is made using cement M400 and M500. In addition, the composition of the mixture contains gravel, sand, and in some cases various additives, including antifreeze. In order to prepare concrete of different grades, it is necessary to take different ratios of ingredients. If the work requires the use of concrete with the presence in its composition of cement M400, you have to use the ratio of cement, sand and gravel in the following proportions: 1:4,6:7. It will be possible to obtain concrete of grade M100.

In order to prepare a mixture M150 using cement of the same brand, it is necessary to apply materials in the same sequence with the following proportions: 1:3,5:5,7. To prepare the solution M200 need to take the ingredients in the ratio 1:2,8:4,8. To produce a specific grade of concrete the proportion of concrete should be studied well before working. So, in order to prepare a mark solution M250, you will need to connect components using the proportion, in which the first ingredient should be applied in quantities of one part, the second – in the amount of 2,1, and the third – and 3.9. Concrete (grade 300) are obtained at a ratio of 1:1,9:3,7. For the preparation of the composition of the brand M200 need to mix the ingredients in a ratio of 1:2,8:4,8. To get a mix of mark M250, you will need to connect components using the mixing ratio should be one part of the first component, the second part of 2.1 and 3.9 – third. Product brand M300 work with the use of the ratio of 1:1,9:3,7.

To prepare a particular grade of concrete the proportion of concrete you can use the ones presented in the article. In order to obtain a solution, which will have a brand M400, you will need to connect the components in the ratio 1:1,2:2. Product brand M450 is formed, if the use of principal components in the ratio 1:1,1:2,5.

The Proportions for concrete using cement M500

Can be used when mixing mortar cement M500, then the same components are connected in a different proportion. So, for the preparation of M100, it will be necessary to mix cement, aggregate of sand and gravel specially prepared in a ratio of 1:5,8:8,1. For receiving the process solution M150 need to add into the mixer the ingredients in the ratio 1:4,5:6,6. If the mixing is to use the ratio of 1:3,5:5,6, you get the M200. Concrete M250 will be able to, if you add all the components in the ratio, which looks like the following – 1:2,6:4,5.

To receive in the course of the construction works of a particular grade of concrete the proportion of concrete must be observed. This will allow to obtain a mixture with the desired quality characteristics. Grade of concrete M300 happens when you use a ratio of 1:2,4:4,3. The M400 is obtained if we apply a ratio of 1:1,6:3,2. Solution M450 will be able to shut, when scheme 1:1,4:2,9.

Characteristics of the mixture

The Builders know what kind of cement to use in making some form of concrete. This is determined by the types of work that are expected to produce. The higher the quality of cement, the smaller the amount you will need to get the solution. Grade defines the strength of the material in compression, but this value can be set only after the design is made sustainable, and it usually occurs after 28 days. In construction the most common mixture that is determined by the marks from 50 to 550.

Scope

The grade of concrete and their characteristics presented in this article will allow you to make the right choice for producing high-quality design. The technology of preparation of the solution and its proportions are determined by the type of works and purpose of the object. M100, for example, found its application in the pouring of the Foundation of the belt type and monolithic slabs. This mixture must be laid with a thickness in the range from 5 to 10 cm Quite often, such a composition is used when carrying out road construction, in addition, it is indispensable in the preparation of the basic installation of the coating. If to carry out comparison of this compound with a M150, then we can say that the last option is well suited for a floor screed, fill the sidewalk, and also the manufacture of the tape base.

Table of concrete quite often helps beginners to masters. Solution M200 can be applied not onlyin the private and industrial construction. Most often it is used in the construction of low-rise buildings, pouring concrete blocks and pavement slabs. Despite the fact that the M250 has a more impressive strength, it is not as popular in private construction. It is usually used when pouring flights of stairs, pavings, foundations, solid fences, as well as in solid Foundation construction.

Concrete (grade 300) is the most common in roads, pavings or slabs, and pouring sidewalks. The same should be said about mark 350. Such mixtures can be called universal. M400 can be used for decorating all kinds of designs for any purpose. Poured this concrete designs require special operating conditions. It is worth mentioning M500, it is indispensable for the construction of dams, weirs and constructions which should be of high strength.

About the quality of the cement

In the construction during the construction of foundations most commonly used concrete M200-M500. It is worth remembering that not only the correct mixing and application of correct proportions are key to producing a solution of sufficient quality. If you use cement, which was kept long or the wrong way, at 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 must be stored in a dry place, and apply the it is recommended as soon as possible after purchase.

The Price of the solution

If you decide to use in the construction of the concrete brand, the price and quality of which are different, be sure to examine the main characteristics of this building material. Talk a little bit about the financial part of the question. Concrete grade M100 will cost 2100 rubles. While the price of M150 is slightly higher than the figure – 2250 rubles. For concrete M300 will have to pay 2800 rubles.

In conclusion

It is Worth noting that grade of concrete – a rather important component in the process of construction or repair work. This characteristics will depend on the strength of the structure after hardening, duration of life of concrete, water resistance and qualities which determine the resistance to low temperatures. Mark defines the index that measures the compressive strength. This characteristic is determined in kilograms.

If you want to construct a structure with a more impressive quality characteristics, it is necessary to use concrete with higher compressive strength. However, the same composition can be obtained if you apply different brands of cement. Do not assume that using more expensive material will fail to save. On the contrary, if you apply more high-quality cement, then during the mixing of the solution it will need much less than one that has not as of high quality and able to provide the desired viscosity. After you have studied the grade of concrete and their characteristics, you can begin to work.
