Sand concrete is a building material that is becoming more and more popular with consumers. At the moment, there are a large number of manufacturers making similar products. Technologically, sand concrete is divided into grades, each of which needs a detailed review.

Features of sand concrete M300

It is worth starting with the fact that this type of sand concrete is the most popular among ordinary consumers. And there are certain reasons for this. The main ones are the density and reliability of the material, which are caused by individual characteristics. Among them, one can note a large fraction, reaching 5 mm. Besides, The M300 has a long walking time (48 hours), so you can make changes as long as the sand starts to harden.

The average temperature range from 0 to 25 degrees allows the material to be used in different climatic conditions. The layer thickness, unlike other raw materials, can be from 50 to 150 mm.

This feature makes it possible to perform tasks quite quickly, especially if the working area is large. The consumption of the mixture depends on the specific technical methods of manufacturing, but in general it is 20–23 kg per 1 sq. M. meter.

A pot life of two hours gives the worker the ability to properly distribute the mixture according to his construction plan. The M300 is versatile, as it is great for both interior and exterior decoration . The maximum pressure level that can lead to the destruction of the material is 30 MPa, which is why this brand can be called very strong and reliable.

The popularity of the M300 is also due to the fact that it represents the best price-quality ratio . Because of this, this mixture has a very wide range of applications, ranging from household and simple tasks to large construction projects. After applying the material according to the technology, it can be used at temperatures from -35 to +45 degrees.

Characteristics of grades M200 and M250

These options for sand concrete have less preferred characteristics than those of the M300, but this disadvantage is compensated for by a lower price. Pot life is 2 hours, the recommended layer thickness is from 10 to 30 mm . It is this feature that makes it possible to characterize these brands as material for the construction of small and medium-sized volumes. The density of the chemical materials that are used to create M250 and M200 begins to manifest itself in 2-3 days, and full hardness will come upon reaching 20 days.

Frost resistance for 35 cycles is enough for long-term operation, since each cycle is an opportunity to absorb a large amount of liquid after melting snow or heavy rains . Water consumption is 0, 12–0, 14 liters per 1 kg of dry mix. This brand of sand concrete has a wide range of applications: surface concreting, floor screed, filling cracks and other vulnerable parts of structures. The available characteristics and their level are best manifested in the domestic sphere of home construction.

M250 and M200 are average quality brands . Professional builders characterize them as models that can be successfully used in simple projects where there are no special requirements for the strength and resistance of the material to weather conditions and other environmental influences. It is these brands that are represented in the largest assortment on the market, since they allow you to perform most tasks without special operating conditions.

Compositions of other brands

Among other brands, it is worth noting M100 and M400. The first variety has the most basic characteristics. Compressive strength - about 15 MPa, which is quite enough for simple construction activities. These include, for the most part, repair. By filling cracks and holes, you can ensure the proper strength of the structure, but in this case M100 should not act as a base, but as a complementary element.

It is worth noting the fine fraction of 1–1, 25 mm, due to which small objects can be processed. The pot life of the solution is about 90 minutes, 1 kg of material requires 0.15–0.18 liters of water.

Frost resistance for 35 cycles is enough to complement the stability of the structure. The tensile strength of this brand is small, due to which it is not recommended to use it as a basis for pouring floors - better models will cope with this better.

M400 is the most expensive and modern mixture . Its main features are very high strength and resistance to various negative effects of the environment. M400 is used in special professional facilities that require a certain amount of advance for the structure. These include skyscrapers, multi-storey buildings, as well as buildings located in not the most suitable areas.

It is this brand that is used when pouring especially durable floors . Viability equals 2 hours, water consumption per 1 kg - 0, 08–0, 11 liters. Manufacturers indicate that the M400 manifests itself best when filled with a thickness of 50 to 150 mm, due to which a large working volume can be performed. It should be noted that this variety requires special storage conditions so that the consumer can get the best result.

Which is better?

The answer to this question depends on what are the goals and objectives of using sand concrete. Each brand has its own characteristics that must be considered before purchasing material. The most popular are the M200, M250 and M300 . The first two can be characterized as the most average, with a wide range of applications. Together with the price, these options can be called optimal for most buyers.

M300 has improved technological indicators, due to which the basis of construction projects, for example, full filling of the floor, is better carried out with this mixture . If you need high quality, strength and resistance to stress, then the professionals recommend this option.
