GRC Concrete in difficult weather conditions

How difficult weather conditions can GFRC products withstand?

Concrete, a commonly known mix of cement, aggregates and water, ceases to be limited to use in the facade of buildings. Now he is boldly looking into the interiors, giving them a fashionable and original expression.

The biggest advantages of concrete in interiors

Concrete in an exposed form looks very attractive, thanks to which it gains a wide range of applications. Ideally suited as an industrial finish of walls, floors or ceilings. Contrary to appearances, concrete accents should not be afraid of the owners of apartments preserved in a classic and cozy style, because the use of concrete is not limited to a strict convention. This material will create a beneficial combination with wood, introducing a note of freshness into a classic interior. In the kitchen or bathroom it works well in the form of an original tabletop. Concrete is a very durable material, but can achieve the assumed parameters only if you follow the appropriate rules when pouring and care. An important factor influencing the mixture are atmospheric phenomena. Any precipitation such as rain, hail, snow, damage the surface of the concrete and cause rinsing of the cement paste. Water that collects on the surface penetrates into the concrete structure, and after evaporation leaves in it a network of channels and voids.

It significantly reduces the quality of concrete, increases absorbability and weakens resistance to frost. The conditions of corrosion protection of reinforcing steel also deteriorate. If there is a risk of precipitation and concreting must be made, it is necessary to remember about proper protection of the built-in element. The wind also has a negative influence on the concrete. During windy weather the rate of water evaporation from concrete is much higher. As a result, there are no conditions for the proper hydration process of cement, which is followed by a decrease in strength. Particular attention should be paid when concreting during periods of low temperatures.

The gfrc products delivered to the construction site should have a temperature of not less than + 5 ° C. After installation, it should be protected against heat loss, eg by covering with a layer of mineral wool and construction film. There are ways to manufacture, transport and incorporate the mixture at subzero temperatures, for example by adding anti-frost admixtures that accelerate binding. However, this does not absolve the concrete recipient from protecting the element against frost.
