M150 concrete - technical characteristics and features of

Concrete M 150 is classified as lean concrete, which is used to manufacture structures that are not subject to significant dynamic or static loads. This material is most often used in the implementation of preparatory work, for arranging strip or monolithic foundations of a small area.

The relatively low price together with good technical characteristics ensured the high popularity of this material when arranging screeds and pouring underlay floors.

The most popular brand of concrete

Бетон марки 150 можно по праву считать наиболее популярным в своем роде, поскольку сфера его применения является очень широкой. Но здесь нужно учитывать тот факт, что данный тип состава не отличается особой прочностью, поэтому его следует очень аккуратно использовать при сооружении нагруженных конструкций (читайте также статью «Бетонные балясины – массивные, но привлекательные решения»).

For example, in arranging foundations for low-rise construction, it is allowed to use sand concrete M150, but here it is necessary to consult with experts.

If we talk about the speed setting, the concrete M 150 can be attributed to fast-setting. This fact should be taken into account when carrying out the delivery of the solution to the object and during the work.

Tip! Often in order to avoid premature setting of the composition, plasticizers are added to it, which are designed to reduce the rate of hardening. They are used when pouring large area designs.

After casting, the compound must gain strength within three weeks. Only after this period does the concrete receive the necessary strength characteristics, and the concrete structure can be put into operation.

The composition of concrete M-150

The composition and proportions of concrete M150 per 1 m3 determine its high strength characteristics. Granite, gravel and limestone crushed stone can be the basis for this concrete. Also, the composition of concrete heavy class B12 5 M150 necessarily includes a binder (cement), water and sand.

The proportions of the components are in direct proportion to the scope of concrete and the quality of the cement used. The consumption of sand concrete M 150 is also largely determined by the scope of its application.

Tip! In many respects, concrete M-150 is no different from the brand M-100. In particular, they have the same indicators of water resistance and frost resistance. Therefore, in some works, for example, in the implementation of the screed, this brand of concrete may be replaced by M-100.

Where is the composition of the brand 150

Peskobeton M 150 is used in a number of areas:

1. To perform general construction work. It is often used in the construction of cottages and other low-rise buildings. If finished reinforced concrete structures are used in construction, it will be necessary to cut the reinforced concrete with diamond circles.
2. Preparatory work carried out at the construction sites. Here we are talking about creating a pillow for the foundations of buildings or for pouring slabs of large sizes.
3. The high characteristics of concrete M 150 make it possible to use it when carrying out a number of preparatory work, such as screed, pouring floors, etc. For example, a screed for the basement, on which practically no high loads act.

1. Road construction, where this type of concrete is used for the arrangement of walkways and sidewalks, as a curb stone and for other purposes.
2. Concrete M-150 is very popular in the field of individual construction, as the fine-grained fillers present in its composition make it possible to do without special equipment, such as immersion vibrators, vibrating rails, etc. Thus, all the work can be done by hand.
3. In private suburban construction is also used for concreting fence pillars, pavilions, curbs.
4. It is often used for plastering of ceilings and walls and other surfaces that need to be processed and leveled.

Tip! When ordering large quantities of this material, you need to consider that from the moment the mortar is prepared, the concrete will be usable for two hours. Then begins the process of setting, which negatively affects the quality of the solution.

Characteristics of the composition of the brand 150

Consider the main technical characteristics of concrete M150:

1. Brand - 150.
2. Class - B12,5. The heavy class of concrete B12 5 M150 provides sufficient strength when creating unloaded or moderately loaded structures.
3. Mobility - P1-P4. The range of mobility is determined by the amount of water that is introduced into the mixture during the preparation of the solution. This brand does not provide for the use of plasticizers.
4. Frost resistance - F This parameter indicates that the concrete can withstand up to fifty cycles of temperature change without any mechanical damage. Here it is necessary to take into account that this indicator for concrete m-150 is not large enough, significantly limiting the scope of its application.
5. Water resistant - W Speaks about high moisture absorption of this material, which requires pre-laying waterproofing material in the case of use in places with high humidity.

1. Density concrete M150 may vary somewhat. Despite the fact that the proportions of concrete M 150 are clearly stated in GOST, the material of solid aggregate is subject to change, which occupies more than half of the total volume. From this it follows that it is this component that is decisive in calculating the density.

Here you need to consider a few important points. The sand, which makes up about one third of the total volume of the material, has a density in the range of 2.2–2.6 tons per cubic meter. Since cement is characterized by a small mass fraction, it has a negligible effect on the indicators of bulk density. The density of cement is about 3 tons per cubic meter.

Solid aggregate in the cement of this brand is often crushed stone, allowing to significantly reduce the price of the source material. Its bulk density is just over two tons per cubic meter.

Tip! The use of porous aggregates allows to reduce the bulk weight of the material, but at the same time you will reduce the compressive strength, because here it is important not to overdo it.

1. Fast freezing. This characteristic is one of the most important since M150 is a fast-setting concrete. This determines its widespread use in plastering, pouring foundations, etc.

This parameter can significantly save time when filling tracks or arranging retaining walls. In the latter case, the drainage holes most often settle down after the concrete layer hardens. Often, instructions for working with concrete grade M150 provides diamond drilling holes in concrete.

The high popularity of this building material in the first place justifies a reasonable price. It is slightly more expensive than the M100, while possessing the best strength characteristics, but much cheaper than the M200.

Conclusion

The classification of this brand of concrete as lean makes it impossible to use it in the construction of large loaded structures. Nevertheless, the scope of application of this brand of concrete mix is ​​quite wide: from foundations for light construction to leveling surfaces (learn here how to choose a circle on concrete).
