High-strength building materials like concrete M350 are frequently used in construction projects that call for resilience and durability. Because of its exceptional compressive strength, this kind of concrete is well-suited for building heavy-duty structures like industrial floors, high-rise buildings, and bridges. Making educated decisions for their projects can be facilitated by builders and engineers having a thorough understanding of the properties and composition of Concrete M350.
The high compressive strength of Concrete M350—typically about 350 kg/cm²—is one of its key characteristics. This qualifies it for locations that experience high loads and stress. Concrete M350’s mix design calls for precise ratios of cement, sand, gravel, and water in addition to any potential performance-enhancing additives. The strength and workability of the concrete are guaranteed by the precise balancing of these elements.
For Concrete M350 to have the desired qualities, its composition is essential. Compared to lower grades, it typically has a higher cement content, which adds to its strength. To guarantee appropriate bonding and structural integrity, the aggregates—such as sand and gravel—are selected based on their size and quality. Furthermore, a precise amount of water is added to obtain the desired consistency and workability without sacrificing strength.
Because of its dependability and versatility, concrete M350 is frequently chosen in the building industry. Because of its durability and ability to support large loads and challenging environments, it is a reliable option for important infrastructure projects. Building professionals can guarantee the longevity and success of their structures by comprehending the primary attributes and composition of Concrete M350.

Technical characteristics of concrete M350
Among the primary indicators on the list are:
- Strength. Concrete M350 has a strength class of B25 – this means that the monolith after hardening and gaining strength does not crack under the influence of a compressive load of up to 25 MPa. Such results are achieved due to the high percentage of Portland cement in the solution.
- Plasticity. This indicator is in the range of P2-P4, the introduction of plasticizers allows to increase the mobility of the working mixture.
- Density. Due to its high density, the monolith does not collapse under extreme loads, is characterized by low surface wear. The weight of concrete M350 depends on the type and fraction of the filler, according to current standards, 1 cubic meter of mortar can weigh from 1800 to 2500 kg, but the optimal weight is considered to be 2200-2400 kg.
- Water resistance. The dense structure, absence of pores and air cavities makes the material resistant to moisture absorption. Water resistance level – W8.
- Frost resistance. The structure of the monolith does not lose its integrity after two hundred freeze-thaw cycles. Frost resistance index F200 indicates the suitability of concrete of this grade for use in regions with a harsh climate.
Concrete M350 is a strong, resilient, and adaptable building material that is highly durable. It is a well-balanced mixture of cement, water, sand, and different aggregates that is perfect for heavy-duty construction projects like foundations, beams, and columns. Its primary attributes, which make it appropriate for both residential and commercial applications, include a compressive strength of 350 kg/cm² and outstanding resistance to environmental factors. To guarantee the longevity and structural integrity of your construction projects, it is imperative that you comprehend the composition and properties of M350 concrete.
Composition
The following components make up concrete MZ50:
- Portland cement grade 400 (strength class 32.5) and higher. The higher the strength class of the binder, the stronger the monolith obtained from the solution.
- Filler:
- sifted sand of any fraction, river or quarry, cleaned of impurities;
- crushed stone (if it is not available, it is permissible to use medium-fraction granite or fine-fraction limestone).
- Water. During the preparation of the working solution, the liquid is introduced gradually, in small volumes, until a material of uniform consistency is obtained.
- Additives. According to GOST, the use of special additives for M350 concrete is allowed to improve the properties of the mixture and expand the scope of application of the material. Plasticizers help to increase the mobility of the mixture, anti -control additives increase its frost resistance and make it possible to make monolithic structures at negative air temperatures.
Self -preparation of the solution
Private developers have the option of ordering a factory-made concrete solution or mixing their own on-site with portable mixers and other household items.
To ensure that the properties of the material meet the current standard, it is crucial to precisely follow the proportions of concrete M350. The brand of cement used to make concrete M350 has an impact on the quantitative ratio of the solution’s ingredients.
The mass percentage of dry ingredients is:
| Portland cement brand/strength class | The amount of cement (t) | The amount of crushed stone (t) | The amount of sand (t) |
| M400/32.5 | 1 | 3.1 | 1.5 |
| M500/42.5 | 1 | 3.6 | 1.9 |
The volume ratio of dry ingredients is:
| Portland cement grade/strength class | Volume of cement (l) | Volume of crushed stone (l) | Volume of sand (l) |
| M400/32.5 | 100 | 280 | 140 |
| M500/42.5 | 100 | 360 | 190 |
Dry ingredients are combined in the first step. Partially add clean water until a mixture that is suitable for laying is achieved. In the event that additives are utilized, they are combined with a specific volume of water to create the solution.
The composition of the solution, when it is used, and how the concrete mixture is made all have an impact on the final monolithic structure’s technical and functional characteristics. While homogeneousness is required, mixing time should be limited to five to seven minutes to prevent delamination of the laid concrete. Since the cement in the solution starts to set after a while, concrete needs to be laid within the first few hours of preparation.
Main advantages
Among the material’s benefits are:
- increased strength of concrete M350 – ready-made concrete mass, resistant to destruction under compressive and abrasion loads;
- high mobility of the solution (adding plasticizers increases elasticity) – the material is easy to lay;

- creating coatings of highways, airfields.
The cost of concrete M350
The cost of a concrete M350 cube varies depending on the area and manufacturer. The material is more expensive in an area where it is necessary to import raw materials from a distance. According to GOST, commodity concrete is produced by concrete plants.
Concrete M350 costs, on average, between 3600 and 4600 rubles per cubic meter in Russia, depending on the type of filler and cement brand.
Conclusion
The purpose of Male Concrete M350 is to produce responsibly loaded structures. It’s crucial to get in touch with a reliable supplier who complies with GOST regulations in order to purchase a completed solution. This guarantees that even with high operating loads, the monolith will remain intact.
