Stages and process of preparing a concrete mixture in a concrete mixer

Industrial or individual construction is simply impossible to imagine without the use of building mortars. Pouring the foundation, erecting walls and ceilings, arranging paths, floors, bricklaying, and a mass of other construction processes require the preparation of a concrete mixture.

It is best to mix the concrete mortar in a special mixer – a concrete mixer. Why is it better? Firstly, it is fast and convenient. Secondly, it yields a larger volume of mixture compared to manual mixing. Thirdly, the physical effort saved by builders is invaluable. And finally, the thoroughness of mixing the mortar cannot be compared with manual mixing.

Therefore, we recommend you to Buy a concrete mixer – this is truly indispensable equipment for modern builders, which also significantly facilitates their labor. We offer a large selection of powerful and compact concrete mixer models in the "Stroytekhnik" online store.

The operation of the concrete mixer is regulated by the following parameters:

• Proportions of loaded components;
• Loading sequence;
• Mixing time;
• Taking into account the allowable time of continuous operation.

Composition of Concrete

The main components of a concrete mortar:

• Cement;
• Sand;
• Crushed stone;
• Water;
• Additives.

General requirements for each ingredient are high quality and an up-to-date expiration date.

The quantity and quality of each component generally determine what technical and operational characteristics the concrete will get at the output.

How Concrete Proportions Are Calculated

To obtain durable concrete, it is important to use the initial components in the right quantities. Optimal proportions are taken based on a 1:3:6 ratio for cement/sand/crushed stone. The amount of water is 50% of the mass of dry components.

However, it is important to consider nuances. For example, the moisture content of the sand. The higher it is, the less water is added to the mixture.

Another factor is the scope of application of the concrete. Crushed stone is not needed in the composition of concrete for every type of construction work. It is not added to the concrete mass intended for floor screeding, but in this case, a plasticizer will be needed.

Algorithm for Manufacturing Concrete Mixture

Concrete mortar is prepared and unloaded only while the drum is rotating. The manufacturing process consists of strictly sequential operations:

1. Pouring part of the water (10-15% of the required amount).
2. Alternating addition of ingredients in the required proportions.
3. Pouring the remaining water.
4. Mixing for 10 minutes.
5. Unloading the finished mortar.

It is recommended to fill the drum to half or even a third of its total volume.

As can be seen, the process of obtaining concrete mortar is simple. Having loaded the necessary raw materials and observed all technology requirements (exact composition and mixing time) for obtaining a specific grade of concrete, a ready-made building mixture is obtained in a few minutes.

If the finished mass turns out to be very thick, add water and mix again.

The "Stroytekhnik" online store offers to purchase not only concrete mixers but also other construction equipment, the price of which will quickly pay off in the production of heavy and light mortars necessary for the construction and repair of buildings/structures and the laying of engineering utilities. In addition, it will shorten construction time and significantly ease the hard labor of builders.
