How much rubble in 1 cubic concrete: composition and

In the industry of modern construction uses a lot of different materials, differing in their physical and technical characteristics, composition, scope and purpose. One of the most technologically advanced materials, without which no construction can do, perhaps, is concrete.

Numerous buildings of the most varied architectural form and complexity are erected from it. The basis of each more or less serious structure is concrete as it is a more durable and resistant to operational loads material.

Why concrete is used for the construction of foundations, columns, beams, floor slabs, load-bearing walls and so on? The thing is that this material is able to transform from a dry to a liquid state, forms any form and then, when it solidifies, it acquires a very solid and durable property - to withstand enormous loads.

The amazing characteristics of concrete were known by our ancient ancestors thousands of years ago and actively used this material in the construction of complex architectural structures that have survived to our times in good, almost unchanged condition. What is included in the composition and why, over time, this material not only does not deteriorate, but also becomes even stronger.

In fact, it includes the most common natural ingredients, such as cement, sand, gravel, rubble, tuff, and so on. How much crushed stone is needed for 1 cubic meter of concrete, as well as sand, cement, and other materials for a particular brand of source material is determined according to technological calculations in accordance with the purpose of the material itself.

So, let's consider each brand of concrete separately and find out how much cement + sand + gravel is in 1 m3 of concrete.

Varieties of concrete mixes

Today, all types of concrete are classified according to weight parameters and are divided into three types:

Lightweight type

Shutter this type of concrete by adding to the solution enough lightweight aggregate, which is based on minerals such as shell rock, expanded clay or tuff.

Average weight 1 cu. m of this mass is about ± 500–1900 kg. Sand in this type of concrete plays a key role.

In a cube, its mass is at least 500 kg. In addition to sand, water, aggregates and cement are added to the solution.

Heavy type

The average weight of heavy concrete is about ± 1600–2600 kg. The composition of the mass is already more significant in size aggregate, such as gravel or gravel. How much crushed stone is needed for 1 cube of concrete, cement and sand?

The basis of heavy concrete includes the following binder components:

• Aggregate - crushed stone or gravel about 1000-1400 kg;
• Sand mass is not less than 400-800 kg;
• Cementrecommended by specialists of the brand not lower than M500 in the volume of about 150–500 kg;
• Average amount of water should not be at least 90-210 liters.

Heavy Duty Type

Heavy-duty and very heavy concretes are formed by mixing fillers, such as barite, metal scrap, hematite, magnetite. In fact, these solutions are rarely used in conventional construction, these are super-heavy compounds, the mass of which can be 3000 kg or more. The basis of the mixtures is heavy aggregates, some water and cement.

Feature of the compositions

As stated above, all types of concrete have their own distinctive mass characteristics. In most cases, to carry out most ordinary construction work, concrete of the average weight class of about 2,200–2600 kg per cubic meter is used. m

Note: For the manufacture of high-quality concrete composition is not recommended in the production process to use the CBC (sand mixture with the addition of gravel). It is possible to obtain a concrete mortar from these components, but its quality is almost impossible to determine in advance, nor can the quality of a future building be assessed.

There are a lot of unscrupulous manufacturers and they are not averse to saving on materials, therefore, in some cases, sand and gravel are used as a filler.

The composition of each individual concrete includes various binders, such as gypsum, polymers, silicate and, of course, cement - the most demanded for the production of solid formulations intended for serious buildings. The remaining substances are used for the production of light types of concrete, the so-called cellular, intended for light buildings.

Type of rubble used for the production of concrete

There are several types of crushed stone used to obtain a particular type of concrete:

• Crushed gravel. It is used for the production of concrete brand M400 or below. It is extracted from sedimentary rocks. It is widely used in road and solid construction.
• Granite rubble. It is made by crushing by press machines under the high pressure of granite rock. It is used in the field of monolithic construction as a material for filling hollow pockets.
• Crushed stone slag. It is used as a material for the organization of repair work on the roadway.

• Limestone. The basis of limestone gravel includes calcite mineral, obtained by crushing sedimentary rock. The strength characteristics of this gravel are low due to which the price of the material is low. It is used in the manufacture of reinforced concrete structures.
• Another type of material is recycled. Obtained by crushing such materials as used brick, road construction materials, namely, asphalt. The use of this material for the production of high-quality brand of concrete is not possible due to the low strength characteristics of the aggregate. The cost is relatively low.

To the note: Diamond drilling of holes in concrete is carried out with the help of crowns on the working cutting surface, with which a special method is applied to heavy-duty diamond spraying. Drilling, as well as cutting of reinforced concrete with diamond circles, is carried out using a volumetric amount of water.

How much rubble in a cube of concrete? On average, 1 cu. m. used at least 1000 kg of gravel, given that 1 cu. m. material weighs about 1500 kg.

We draw conclusions, watch the video on the topic

Now you have a detailed idea of ​​what concrete is, what it is used for and how much concrete, crushed stone, sand, cement is needed for a cube, and in what proportions all these materials are used to produce a particular brand of concrete.
