ASV concrete products have CE certification in accordance with the EU Construction Products Regulation. With certified concrete products, construction is safe and suitable for a wide range of projects as well as for public-building and private-home construction.

Concrete will not burn or melt

Concrete is a non-combustible building material. In a wooden residential building, the fire load can be more than twice as high as in a concrete building. Non-combustible concrete surfaces can delay combustion relative to flammable surfaces. The heat-charge capacity of concrete binds heat generated by fire better than well-insulating and lightweight surfaces.

A concrete building can withstand a fire without collapsing

Apart from some thinner walls, a concrete building will last at least an hour in a standard fire. With thicker structures the fire resistance can be increased to up to four hours, which means that a concrete building can last for the entire duration of a fire without collapsing. The collapse of concrete buildings in fires has not occurred much.

Concrete is moisture-resistant and does not mildew

Concrete structures tolerate quite a bit of moisture. They bind moisture only a little and on the other hand, the transfer of moisture occurs slowly. In case of sudden water damage, it is usually sufficient to simply dry the concrete structures with no need to replace them. Surface coatings and wet wood components, as well as wood-board siding, have to be replaced almost invariably.

Concrete Also Protects Against Radon

For example, concrete is used in the radiation-shielding structures of hospitals. For this purpose, an extra-heavy class of concrete has been developed and the structures built with it are effective barriers to the spreading of radiation. The most widely known example of radiation is the odorless, tasteless and invisible radon gas emitted from radium.

Tight structures are the best defense against radon gas

According to the decision of the Ministry of Social Affairs and Health Finland, the radon concentration in housing units should not exceed 400 becquerel per cubic meter (Bq/m3). New housing units are to be designed and constructed in such a manner that the radon concentration will not exceed 200 Bq/m3.

When the floor, walls and ceiling are concrete, they produce a radon content of about 70 Bq/m3 in the housing unit, which is about one third of the design value of a new house and one sixth of the maximum value allowed for a residential house.

The most significant factor affecting the variation of radon concentration is the flow of radon-containing air from the ground. In practice, exceeding the threshold, as decided by the Ministry of Social Affairs and Health Finland, is possible only if a high radon emission from the ground enters the housing unit. 

As a building material, concrete is a good absorber of radioactive radiation, since radiation attenuation occurs exponentially in relation to mass. This property is useful in areas, where the ground has a high level of radiation.
