How much concrete is there in a cube: cement, sand, crushed stone?

Modern industrial and private construction is not complete without the use of concrete mix. The brand defined for concrete has unique characteristics that are taken into account when arranging the foundation and frame bases in various buildings and structures. All physical and technical parameters are affected by the proportions of the components of the concrete mass, namely cement powder, sand and crushed stone. Let’s take a closer look at the content of all the components that make up a concrete cube.

Types of concrete compounds

Before thoughtlessly combining sand and cement , adding the first crushed stone to the mixture, the employee should determine as accurately as possible which of the functional types the resulting concrete grade should subsequently belong to. According to the scope of application and properties, there are several varieties.

• Lungs. The weight for 1 cube of this consistency can vary from 500 to 1080 kg. Instead of crushed stone, it is necessary to add soft types of fillers (perlite, expanded clay, seashell) to cement and sand.
• Heavy ones. The weight value increases to 1600-2600 kilograms. This type is most popular when capital construction works are being carried out. As a filler for it, use the usual crushed stone placer, or select the appropriate fractions of gravel similar to it.
• Super heavy ones. At maximum strength, 1 cube of concrete weighs 3000 kilograms or more. Strengthening role is played by hematite, Berite, magnetite and metal scraps. Mainly, the production of such concrete consistencies is carried out in the factory according to the customer’s requirements.

Next, we will talk directly about heavy concrete consistencies and how much crushed stone, sand placer and cement powder is needed to produce them.

Optimal CPU ratio

The key task of the worker when mixing materials is to determine the most correct amount of cement, sand and crushed stone placer. We will consider how much each of the consumables is needed, we will calculate the partial parts of these elements in 1 ^m3 of concrete consistency. In order to get a really high-quality mixed concrete composition, it is customary to use the highest grades of cement. Numerical values are presented in a summary table.

The final density and other parameters of cement (1 cubic meter) depend on how accurate the measurements were and how correctly the batch was made. You can also combine CPSS for large volumes of concrete consistency. In order not to perform eye measurements, you can study other articles on our website, for example, what is the volume value for a 50-kilogram bag of viscous powder.
