Concrete V20 M250

The composition of concrete B20 includes cement, fillers and water. In addition, various chemical and mineral additives can be used to improve performance.

Production proportions: 1 / 2.6 / 4.5 (cement / sand / crushed stone).

A reader who is not related to construction may be asked the question: what is the difference between mineral additives and ordinary filler?

In addition to their quality characteristics, they differ in smaller size. Due to this, additives can increase the density, fill the voids, and thus improve the quality. Because of this, it can be used for construction work even at sub-zero temperatures. Only it is necessary to immediately take into account that the use of such technologies affects the final cost of the product.

• Most often it is used when you need to make a monolithic foundation.
• Great for decorating stairs, walkways, retaining walls.
• Used for the manufacture of interfloor ceilings.
• Often used to equip structures that do not require very high strength characteristics. Namely, for the manufacture of small supports for racks, pipelines, etc.
• Production of reinforced concrete structures, by the type of foundation blocks and rings.

It is considered one of the most optimal for a combination of relatively low cost and high performance technical characteristics.

The B20 M250 brand is almost as good as the M300, but it is still different from the more popular M200. From the latter it is distinguished by another level of strength. So, it is 260kg / cm2. Despite the advantages of this brand, when it comes to pouring the strip footing, it is still better to prefer the brand M300.

If desired, the customer can change the permeability (W). So, after adding special additives, this parameter can be raised from W2 right up to W8. But it will affect its value.

It is possible to transport B20 concrete, using the auto concrete mixer. At the work site, it is supplied by a special pump for such purposes.
