Peskobeton 300is a composition (a type of dry mix) that is used for arranging foundations and floors (screed), concreting structures or leveling any surface. It is a convenient and practical building material for which both internal and external use is allowed. When the composition solidifies, its excellent physical and technical characteristics and positive operational properties are manifested.
Structural components for sand concrete mix
The composition of sand concrete 300 is produced within the limits of the production standard GOST 7473-94. a dry powdery mass is obtained from the following materials:
- vintage Portland cement, mainly M500 D20 / M400 D0;
- well-dried sand of combined fractions;
- various additives (frost resistance enhancers, plasticizers, microsilicon, fiber), introduced at the discretion of manufacturers.
Directly from the fractional type of sand depends on the sphere in which the resulting mixture is used.
| Particle size, mm | Advantages of building materials | Where it is used |
|---|---|---|
| Small (0.8-1.2) | Increased wear resistance and strength level. | Responsible masonry and other types of work carried out on the street, as well as pouring floors (up to 5 cm in thickness) and the ability to create a high-strength installation solution. |
| Medium (1.8-2.2) | It tolerates operating conditions well. | Interior decoration of the premises, laying curbs and tiles, construction of fences. It also creates a high-quality floor layer (up to 10 cm) with the possibility of installing a heating system. |
| Large (2,5-4) | Moderate moisture absorption | Suitable for capital construction (slab, strip or columnar foundations). There is no restriction in the size of the poured coating (reinforcement is required). |
The proportions of component elements-C to N are approximately 1: 2 (parts of the total weight). In fact, each characteristic and functional capability that a given construction mass has depends on the proportional ratio of structural elements and how much chemical impurities were included to obtain it (the more, the better).
Important! An additional element when kneading is pure cold water (up to 20 degrees Celsius). Its fractional inclusion in the overall consistency of the masonry mass also plays a significant role in the formation of quality indicators.
Key advantages on the example of the product
The building material chosen by us as an example is the same universal mass as other sand-concrete combinations from reputable manufacturers. When buying them for your own purposes, you should consider the following positive opportunities::
- it is characterized by a complete absence of shrinkage, which allows you to immediately proceed to the repair (finishing) processes after filling.;
- the mass of ready-made sand-concrete building materials is plastic and dries much faster than alternative products;
- the mass of this brand, hardens well, is resistant to mechanical impact and other negative factors;
- objects made from used building materials are durable, environmentally friendly and moisture-resistant (hydrophobicity allows you not to be afraid of deformation of brick or precast concrete walls even in excessively aggressive environments);
- all products require high corrosion resistance and the like.
An acceptable price for the wholesale purchase of building materials should also be indicated. The advantage will be the optimal consumption of the product, as well as the ability to calculate with the help of professionals how much building material should be purchased for a variety of technological cases.
