Today, concrete is an indispensable material in construction. Many brands are used in the course of such work - from 100 to 500. Each has its own special purpose. Concrete M-100 is used in construction mainly for preparation before carrying out subsequent work.
General characteristics
Concrete brand 100-M belongs to the type of light solutions. It is used in the creation of load-bearing structures, ebbs, gutters, before pouring the foundation of a building, as well as monolithic slabs. Now it is a necessary material at any construction site, whether it is a garage or a high-rise building. The concrete of the presented brand has a limited scope of use due to its low strength. There are a lot of varieties of concrete.
The use of 100-M concrete is appropriate for the construction of roads, footpaths, sidewalks, as well as for preparing the foundation for subsequent work.
Concrete grades
The brand of concrete depends on the constituent components that were used in its manufacture. It also indicates the strength and performance characteristics of concrete. Mainly to obtain a high grade indexuse a larger percentage of cement during the preparation of the mortar.
There are many varieties of concrete grades. Each has its rational scope:
- M100 - used for buildings that will be subjected to minimal loads in the future.
- M150 - its differences from the previous category are minimal. The scope is the same.
- M200 - used in the production of reinforced concrete belts, as well as floor slabs.
- M250 - the difference is small from the previous brand, so it is rational to use the solution in the same way.
- M300 - great for making landings, roads on which heavy traffic will occur.
- M350 - analogue of concrete M300. Used in the construction of critical structures.
- M400 - used in the construction of building foundations, as well as a bearing layer. Ideal for sites where the strength of the floor is an important criterion for the final result.
- M450 is one of the strong concrete grades. It is used in the construction of critical structures. Guaranteed to withstand heavy loads. Used to make high-strength load-bearing slabs in the construction of building foundations.
- M500 is the strongest and most reliable concrete. It is used in construction, where extreme reliability, guarantee, quality and durability of the finished structure are needed. Concrete brand 500M provides long-term operation of the building, reliability in the harshest conditions.
According to the characteristics of constructionworks select the required type of solution. The cost of the material directly depends on its brand.
Composition
In the manufacture of the mixture, the amount of cement in the solution is minimal. Not the heaviest concrete 100 M has a field of application designated by building codes. Because of its structure, the material was given the name "lean concrete". It is more rational to use it for binding aggregate particles.
Also, the composition of the mixture includes crushed stone, which can be gravel, granite and limestone. Cement grade 400 or 500 is taken as the basis.
Preparations and proportions
In the manufacture of the solution, the established ratio of components is maintained. More often, the proportions of concrete 100 M 1:4, 6:7 (in the sequence of cement / sand / crushed stone) are used when using cement M400. If the composition includes the material M-500, the ratio changes somewhat. The solution is prepared in a ratio of 1:5, 8:8, 1 in the above sequence.
Low requirements are put forward for such concrete in terms of strength. Therefore, no additives are used in its manufacture. Without additional components, concrete 100 M is not able to demonstrate a high level of frost resistance and water resistance. This limits its scope. The level of frost resistance reaches 50 cycles of freezing and freezing, and water resistance corresponds to the category W2.
Scope of application
Concrete 100 M is used for non-critical work in the construction of non-load-bearing concrete structures -blind area. Its use is rational when installing curbs, since they do not need additional strength of the underlying layer. Due to the fact that the load on the product is allowed to be small, it is possible to use it when moving along the road of pedestrians, and not cars.
You can use the presented material for roads with minimal traffic, such as a garage, yard, etc. A similar mortar is used for preparatory work before pouring the foundation of a building.
Preparation of the bases is carried out by thin-layer pouring of concrete M 100 on a pillow prepared in advance from crushed stone and sand. After that, a waterproofing layer is arranged. Only when it hardens, subsequent reinforcing work is carried out. The concrete of the presented brand is one of the many varieties that differ in the ratio of the constituent components. Therefore, each brand of cement slurry is intended for use in a specific job due to its performance characteristics.
For serious work, in the course of which basic, fundamental objects will be created, stronger solutions are used. If concrete products will be subjected to high loads, the presented concrete 100 M is not used. This is its disadvantage. But the cost of this material is lower than that of other brands.
Recommendations from experts
Experts recommend when choosing concrete to take into account where it will be used, what loads it will be subjected to. You should also pay attention totechnical indicators, concrete grade in terms of compressive strength (kgf / cm²).
Having considered the features of the use and manufacture of concrete grade 100 M, it is possible to correctly apply the material presented in construction work.
