What is dry density of concrete

Weight per cubic meter: How heavy is 1m³ of concrete?

How heavy is concrete and how much does one cubic meter of it weigh? This is basically not a difficult question if you know the density of concrete and know that a cubic meter is 1 x 1 x 1m, i.e. 1m³ or 1,000 liters. In this guide we would like to show you how much 1 m³ of concrete weighs can - because not every type of concrete has the same density and therefore weighs the same. There are different types of concrete, with different densities and thus also with different masses per cubic meter (weight = volume x density).

Weight per cubic meter: How heavy is 1m³ of concrete? Here you will find answers to this question, also with regard to lightweight concrete, heavy concrete and other types.

Do-it-yourself concrete: weight of concrete at home

The single ones Components of concrete differ from one another in their density, but for concrete, which is used by do-it-yourselfers and largely in house construction, a rule of thumb can be drawn up from which the weight of 1m³ concrete can be derived. Because mostly 300kg cement with 1,890kg aggregates and 180l water are mixed for the do-it-yourself concrete in order to get one cubic meter of concrete. If you add up all the weights, you get 2,370kg of fresh concrete. For example, if 60m² of flooring is to be provided with 5cm of concrete, you would need 3m³ of concrete; and this would weigh 7.11 tons in the fresh state. You can specify the exact need for concrete for your individual project this concrete calculatorto calculate.

Cubic meter weights in comparison: concrete, sandstone, gravel

To put the individual values ​​in relation to each other, here are a few details that were taken from a training table for crane operators of the professional association for the construction industry. In addition to the 2.37 tonnes of fresh concrete weight of the "do-it-yourself version", you receive a few values ​​from professional construction sites:

Building material / mixture of substancesWeight per m³
Concrete made from gravel2.300kg or 2.3t
Reinforced concrete2.500kg or 2.5t
Sandstone2,600kg or 2.6t
Sand and gravel dry1,800kg or 1.8t
Wet sand and gravel2,000kg or 2.0t
Loam and clay2.100kg or 2.1t
Stone gravel1,800kg or 1.8t

Dry density of normal concrete, lightweight concrete and heavy concrete

The values ​​given in the table above are basically only guidelines. When calculating the mass, exact volume and exact density of cement (clay and lime), rock (gravel or sand) and additives are necessary for exact values. If you do not know this information and therefore cannot carry out your calculation yourself, you can use the above figures or the following mass values ​​for normal concrete, lightweight concrete and heavy concrete (dry density), which are broken down again:

  • Normal concrete: 2,000 and 2,600 kg / m³
  • Lightweight concrete: less than 2,000 kg / m³
  • Heavy concrete: from 2,600 kg / m³

Determination of the bulk density according to the corresponding class

1 m³ of lightweight concrete can have different bulk densities depending on the stones it contains or the amount of expanded clay used. If you use lightweight concrete, you can already pay attention to the corresponding classes when buying. These are divided into the following individual values: 1.0; 1.2; 1.4; 1.6; 1.8 and 2.0 - the numbers indicate the density of lightweight concrete between 1,000 and 2,000 kg / m³.

Answers to the most important concrete questions

On this page you will not only learn how to calculate the weight of concrete with density and volume or how heavy a cubic meter of concrete is on average, but also much more about the versatile raw material. Because on the one hand you can Concrete furniture on the other hand, it is used for bridges, breakwaters, roadways, houses and much more. There are even concrete roof tiles. From the floor to the walls to the roof and in the interior, the building material is represented. Due to the comparatively low costs, this is also very understandable. Here you will find another guide with answers to important questions about the material: Calculate concrete: How many kg of ready-mixed concrete do I need for 1 m³?

Calculate the volume of bodies in m³

If you take a cuboid or cube as an example for calculating the spatial dimension (volume), then simply multiply the height, width and depth of the body. It is important to ensure that all values ​​are calculated in meters, even if they are below 1. At the end a value in m³ comes out. A cube with the dimensions 2 x 2 x 2 m has a volume of 8 m³. If you want to calculate the spatial dimension of a cuboid, you usually have unequal factors; for example 2 x 3 x 0.5 m. These dimensions result in 3 m³ at the end of the calculation.

Of kilograms, tons and building protection

If you want to mix or order concrete, the first thing you need to know is what volume you want to fill and how many kilograms or tons of the individual components such as cement (clay and lime), rock (gravel or sand), additives and water you need. Please also note that the concrete will still dry out after pouring and spreading. It takes at least 28 days for concrete to dry out before it can be walked on or built on. It often takes months or years to completely dry out. After a month or two you can or should be able to work on concrete as much as possible to brush. If you do not know whether the resulting weight can be held by the subsurface or substructure, it is better to ask a structural engineer.

Questions, answers and help

If you buy your own mixing mixes in hardware stores or wholesalers, you can ask the specialist staff there to help them choose the right concrete. If necessary, ask about lightweight concrete or the best type of concrete for your specific project. You can also contact manufacturers and ask for the appropriate answers. The individual skilled workers know how heavy the “wet” and the “dry” concrete is that they produce or sell. If you want to work in steel, you should also consider its volume and weight. Steel has a density of 7.85 to 7.87 g / cm³.
