Where it is used

Because sand concrete M200 has a good composition, it is used extensively for a variety of tasks in a wide range of fields. Due to its high drying rate and low shrinkage, the solution is most useful for finishing and installation work in low-rise industrial and residential building projects.

  • Concreting of various structures that are not expected to be exposed to too serious loads
  • Laying different types of blocks and bricks
  • Sealing of recesses and cracks
  • Foundation pouring
  • Work on leveling floors, walls, ceilings, grouting joints between blocks
  • Preparation and pouring of floor screeds (especially relevant for heated floors)
  • Pouring of walls, other vertical structures
  • Improvement of the local area – pouring pedestrian paths, garden paths
  • Restoration of various surfaces

On horizontal and vertical surfaces, the solution (sand concrete M200) can be applied in thin or thick layers. Because of the mixture’s composition, buildings’ technical qualities can be greatly enhanced, and the dependability and durability of structures can be ensured.

Composition

The proportions of various components in sand concrete M200’s composition are governed by GOST 31357-2007. The primary components and their volumes (as well as the precise parameters) must not change, but manufacturers may make small changes to the dry mix’s composition to enhance its qualities and accomplish the intended results.

  • Portland cement grade M400
  • River sand of fine and coarse fractions – must be thoroughly pre-cleaned from impurities
  • Fine fraction crushed stone
  • Water
  • Additional dry mixes – plasticizers, additives, special substances
  • 265 kilograms of Portland cement – 1 part
  • 860 kilograms of sand – 2 parts
  • 1050 kilograms of crushed stone – 5 parts
  • About 180 liters of water – the volume can vary

Advantages and disadvantages

Peskobeton M200 is an all-purpose mixture that finds extensive application in diverse fields, such as underfloor heating screeds, bricklaying, pedestrian pathways, and restoration.

  • Relatively low material price
  • Simplicity and ease of independent preparation-just buy a BIG-run, read the instructions, add the desired volume of water, mix and use
  • Environmental friendliness and safety for human health, due to which sand concrete M200 can be used to implement any tasks, including for interior decoration and screeds in residential premises
  • High drying speed – the solution can be used even for urgent concreting
  • Preservation of the original appearance for a long time – sand concrete is not subject to cracking, deformations
  • Squeezing sufficiently resistance to compression on calculations
  • A good level of frost resistance is even higher than that of many higher concrete classes (provided that special additives are included)
  • Low thermal conductivity
  • Significant improvement in sound insulation performance
  • Maintaining properties with sudden temperature changes

There are very few drawbacks to the material, including its relatively large packaging (the minimum weight is 25 kg), its water permeability (provided no special additives are added), and the necessity of closely monitoring the amount of water used to prepare the solution (no more than 20% of the total weight of the solution).

Working with sand concrete M200 does not require special knowledge and skills, it is quite possible to cope with all the stages on your own. The container always contains instructions with exact volumes, a description of the preparatory, main work.

Technical properties are enhanced by the use of special additives, which also increase corrosion resistance, frost resistance, and plasticity. These additives also prevent the growth of mold and fungus. Furthermore, pigments that give the solution the desired shade can be added to give it a specific color.

Knowing how much material you’ll need per square meter, the important technical characteristics to look for, and the proper ingredient mix are all crucial when making sand concrete. This guide outlines the essential qualities like strength and durability and breaks down the basic consumption rates, such as how much sand, cement, and water you’ll need. You can guarantee the strength and dependability of your concrete project by paying attention to these details.

Features

Peskobeton is frequently regarded as a component in between concrete mixture and cement. Dry material is frequently utilized in construction, repair, and restoration projects. It does not shrink, is lightweight and simple to work with, and has shown to be effective on shaky soils. In the construction of concrete floors with significant loads, such as those found in garages, warehouses, and shopping centers, sand concrete M200 is essential.

Crushed stone and chemical additives in the mixture ensure that the material won’t shrink, even when the layer is fairly thick. Plasticizers can be used to increase strength while also offering a high enough degree of frost resistance.

It’s important to accurately calculate the ideal volume when adding different additives, especially to give the mixture workability, so that the desired consistency is maintained without sacrificing the strength characteristics.

Pigments are used to give sand concrete the desired color; a good selection is available in this area as well. Selecting the appropriate additive and following directions are crucial.

Technical characteristics

GOST 7473 regulates all operating parameters that are relevant to concrete M 200 mixtures, and they need to be considered during design and calculation processes. Sand concrete M200 needs to have a minimum compressive strength of 200 kg/cm2. Since the remaining parameters can change based on the kind and quantity of additives, they are shown as averages.

  • Strength class – B15
  • Frost resistance level – up to 150 cycles
  • Water permeability – within W6
  • Bending strength – 6.8 MPa
  • The duration of the "life" of the finished solution is a maximum of 110 minutes (during this time, the mixture must be used, since then the solution will lose its properties)
  • Sand concrete consumption – is largely determined by the evenness of the base, the fraction of filler grains: the maximum is 1.9 kg / m2 per layer thickness of 1 millimeter

Generally, a 50 kg bag can cover an area of 2-2.3 square meters with thin screed. The consumption increases by 1.5–2 times if the base is being set up for heated floors.

Proportions of concrete per m³

Construction standards state that the volume of components used per cubic meter is as follows: 180 liters of water, 4.8 kilograms of additives, 860 kilograms of sand, 1050 kilograms of crushed stone, and 265 kilograms of Portland cement M400. The formula that results from specifying in proportions is as follows: 0.2 percent of the total weight of additives, 1 part cement, 2 parts sand, 5 parts crushed stone, and 0.5 parts water.

Preparation of the solution

Sand concrete M200 is a ready-made, dry construction mixture that only needs to be thoroughly mixed with water and used for 110 minutes of work. Even though the task seems straightforward, you must closely adhere to the instructions and the stages of work.

  • Dry powder is poured into a specially prepared container – it must be dry and clean, of a suitable size
  • Pour in the required volume of water, stirring carefully and thoroughly – it is better to take water at room temperature (in extreme cases, slightly cool)
  • Stir until the solution reaches a uniform consistency and the lumps completely disappear from the structure – for this you can use a drill with a special attachment or a construction mixer
  • Let the solution stand for 10 minutes
  • Stir again thoroughly and use the mixture in work

It is crucial to adhere to the directions: adding more water than called for will weaken the mixture and hasten the propagation of fractures. If everything is applied properly, the coating can easily support a load of up to 200 kg/cm^2.

For 110 minutes, the solution keeps all of its characteristics; after that, the mass is no longer fit for work.

Safety

Sand concrete is applied to a dry, clean surface while the job is being done. All weak spots are filled in and the same mixture is applied beforehand to various cracks and potholes. Grease stains need to be cleaned up completely as well. To raise the finish’s quality indicators, pre-prepared walls are additionally treated with unique strengthening impregnations.

It’s crucial to adhere to the guidelines and apply the mixture in the ideal layer during the task: brickwork should be up to 1.2 centimeters thick, leveling with reinforcement should be 4–10 centimeters thick, and leveling without reinforcement should be 2–5 centimeters thick.

It is essential to rule out drafts and direct UV radiation during the workdays and the first three days. In two hours, the solution sets, and in twenty-eight days (much faster if additives are added to the composition) it attains the desired properties.

It is essential to follow safety protocols while working, such as wearing gloves, construction glasses, and protecting your eyes from the mixture.

The work should ideally be completed when the outside temperature has risen by at least +5 degrees. The solution can be laid in frost if specific components that are resistant to frost are added to the composition. It is recommended to periodically stir sand concrete to prevent it from hardening too quickly in the container.

Sand concrete is a practical option that offers durability and versatility for a variety of construction projects. You can make sure that your concrete mix works well and satisfies your needs by being aware of the proper ratios and technical details. Strong, dependable results can be obtained by using the right amount of materials per square meter and being aware of the characteristics of the mix.

The proper ratios are essential when preparing sand concrete. Standard mixes usually consist of three ingredients: sand, cement, and water, with sand accounting for a large portion of the mixture. Modifying these ratios in accordance with the particular needs of your project will impact the concrete’s strength and polish. Monitoring the consumption per square meter aids in waste reduction and efficient material planning.

The success of your project can be significantly impacted by your understanding of the technical properties of your sand concrete mix, such as its strength, workability, and drying time. You can produce concrete that not only satisfies structural requirements but also withstands environmental conditions by adhering to the suggested mix ratios and making sure that high-quality materials are used.

In conclusion, precise mixing and careful planning are required when creating sand concrete. Correct proportions and technical specifications will guarantee a strong and long-lasting finish that meets your building requirements. Sand concrete can be a dependable and affordable solution for a range of applications with the appropriate methodology.
