Concrete weight: properties of lightweight, heavy, very
In order to build a quality building, it is necessary to take into account all sorts of factors that can be encountered during construction. First of all, it is the weight of concrete in 1 m3, on which the strength of supports and supporting structures depends. When building any structure, it is necessary to correctly calculate this parameter.
General information
During the construction of any objects it is very important to know the weight of all its components, since the mass of the building plays a big role, and the concrete here is of primary importance. Knowing its mass in 1 cu. m, you can correctly calculate the load on the main structure and thereby increase the life of the entire structure. For example, the weight of the concrete sleepers will affect the calculation of supports for it.
All kinds of supporting structures, monolithic foundations, partitions and other building components are mostly made of it. Therefore, to bypass this option will not work.
The weight of the concrete must be calculated at the preparatory stage, i.e. during the design of the object to correctly determine the required amount of material. Thus, at the initial stage, you will have an idea of the possible estimate of the object.
Tip: be sure to carry out such calculations, despite the fact that the price of the solution is not so high. However, it often takes quite an impressive amount.
If you convert m3 of concrete to tons, the mass range is 1 cu. m can be from 500 kg and it depends on various reasons.
This is due to the properties of the material, which can be:
- особо heavy;
- heavy;
- lightened;
- easy;
- сверхeasy.
Of particular importance to the mass is affected by the composition of the filler, which is required to prepare a mixture of the desired quality. After curing, it indicates the strength characteristics of the cast structure.
The composition of the solution also includes various additives and binders. In the manufacture of the solution plays an important role and water, which interacts with the latter. It tends to partially evaporate and this must also be taken into account, since the weight of wet concrete will be higher than dry.
A great influence on the mixture has a binding agent, which depends on the brand of the finished solution. Since these additives and fillers are added to the mixture in large quantities, they significantly affect the final mass.
The main binder in the solution is cement, which has the highest density. He is also the most common material of this property. Consider light formulations, the price of which is below heavy.
Tip: if you do not take into account the requirements for lightweight material, you can not keep within the required parameters, which means that the prepared solution will not match the brand.
| Ultralight or extra light | Since the volumetric mass of the ultra-light composition is low, this solution performs heat-insulating functions. In one cubic meter of the composition of about 500 kg of the mixture. To achieve the desired figure, you must use special processing methods. In this case it is necessary to apply a heave, air is supplied to the composition and pores are formed there, due to which the volume increases. First, the weight of 1 m3 of concrete is calculated, and then a solution of the required density is made. To facilitate the calculation, various tables are used, in which the weight of individual materials is indicated. In particularly light formulations do not apply a mixture having a high density. |
| Lungs | The weight of lightweight concrete is determined during preparation. In this case, there are different ways that depend on the classification. Typically, the bulk density of the material is in the range of 500-1800 kg. This is sufficient for the manufacture of solutions that have sufficiently high performance. The instruction recommends its use in the construction of low-rise buildings, creating supporting structures. In this case, there is often come to a compromise, considering the relationship between the strength characteristics of the structure and the mass of the material. |
Tip: when using a light mortar in construction, be sure to consider the desired strength of concrete structures and the weight of m3 of concrete.
Production is designed for the use of lightweight porous fillers, for example, expanded clay is often used as a filler.
Much less commonly used:
- agroporite;
- artificially expanded slag;
- pens
Although these materials themselves are also well proven. Remember, the correct combination of such parameters — cost and necessary characteristics — leads to the desired result.
Tip: even before construction begins, calculate how much 1 m3 of concrete weighs and its required quantity.
Otherwise, if:
- the mixture will not be enough, you will need to order an additional solution, and in this case a cold joint is formed in the building;
- order more than necessary - it turns out that the money "thrown to the wind."
Lightweight
- This brand is widely used in modern construction, as it has a sufficiently large strength.
- The mass of material in 1 cu. m ranges from 1800-2000 kg.
Tip: use the composition where high strength and relatively low weight of the structure are necessary.
- The filler can be various materials. Most often used crushed stone, which is the most popular in the construction market.
- Be sure to carry out preliminary calculations before starting work, to know exactly how much concrete weighs.
Tip: do not need to exceed the maximum size of the fraction of rubble, which is designed for lightweight composition. To enhance the characteristics of the quality of the solution, use all sorts of additives.
Heavy
- This is the main material for construction work.
- It is used more often than all other brands, since the characteristics are the most suitable for solving a wide range of tasks.
Tip: when calculating how much weighs 1m3 of concrete of this type, consider the weight of the filler, which can be diabase, limestone or granite.
From the filler also curled and the volume of the composition, which also needs to be considered. Usually the mass of 1 m3 of such a solution is 2100-2500 kg.
Most often, the material is used when pouring it by hand or by mechanizing monolithic foundations. If it is necessary to apply reinforcement, please note that the weight of the structure will also be increased.
Especially heavy
- This composition is quite rare in construction, as its characteristics are very rarely used.
- When calculating the mass of a heavy solution, you should also consider the weight of the filler, as you did in the previous paragraphs.
- From the concrete of this brand is expected to very high strength. Sometimes you may even need protection from radiation. If necessary, lead shavings or iron ore are added to the mixture. In this case, the mass of the material also increases.
Based on all calculations, it is possible to understand how much 1m3 of concrete of this type weighs, but usually this figure is much higher than 2.5 tons and higher.
Since this is a very durable material, it is used:
- for the construction of underground parts of buildings;
- as the bases of large objects.
It is not used anywhere else, since the weight of the fabricated structure will be significant.
Conclusion
From the article it became clear that the main component that affects the weight of concrete in 1 m3 is a filler. This is usually crushed stone, but limestone or granite can also be used for superheavy materials, as opposed to particularly light and light, where swelling is used.
Knowledge of the mass makes it possible to correctly calculate the strength of concrete pillars or the foundation, as well as save money. The video in this article will help you find additional information on this topic.
