Concrete B20 M250

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

Proportions for manufacturing: 1 / 2.6 / 4.5 (cement / sand / crushed stone).

A reader who is not related to construction may have a question: how do mineral additives differ from a conventional filler?

In addition to their quality characteristics, they differ in their smaller size. Due to this, additives can increase density, fill voids, and thus improve quality. Thanks to this, it can be used for construction work even at sub-zero temperatures. Just 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 arranging stairs, paths, retaining walls.
• Used for the manufacture of interfloor ceilings.
• It is often used to equip structures that do not require very high strength characteristics. Namely, for the manufacture of small supports for overpasses, pipelines, etc.
• Manufacturing of reinforced concrete structures, by the type of foundation blocks and rings.

It is considered one of the most optimal in terms of a combination of relatively low cost and high performance indicators.

The B20 M250 grade is practically not inferior in strength to the M300, but at the same time it still differs from the more popular M200. It differs from the latter by a different level of strength. So, it is 260 kg / cm2. Despite the advantages of this brand, when it comes to pouring the strip foundation, it is still better to prefer the M300 brand.

At the request of the customer, you can change the water permeability (W). So, after adding special additives, this parameter can be raised from W2 right up to W8. But this will affect its cost.

Concrete B20 can be transported using a concrete mixer truck. It is supplied to the working area by a special pump for such purposes.
