  • What does a drainage channel have to do with a volcanic eruption?
    0:00 - Formation of basalt
    Basalt solidified from magma into stone many thousands of years ago. Magma rose to the earth's surface during a volcanic eruption. It came from at least 40 kilometers deep and had a temperature of up to 1200 degrees. As it cooled, the magma solidified into basalt rock. This has been happening for many geological eras - and is still happening today.
    00:47 - Occurrence of basalt
    Basalt is found all around the world. There, too, where there are active and extinct volcanoes, such as in Iceland. Basalt forms spectacular landscapes here. Basalt even exists on Mercury, Venus and Mars, on the moon and on meteorites. There is also a lot of basalt in Germany. It is mined, for example, in the Eifel and in the Rhön.
    1:19 - Material properties of basalt
    Basalt has great properties. The volcanic rock is anthracite to black in color. Because it is formed on the earth's surface by rapid cooling and without pressure, it has a fine-grained microcrystalline and stable structure. This is what makes it so hard and resistant. Another advantage is that basalt occurs frequently and is a purely natural product. Strictly speaking, it is a renewable raw material, because it forms anew with every volcanic eruption. On the earth's surface and in our oceans, thousands of times more basalt is formed each year than we can use.
    2:06 - Areas of application for basalt
    We find basalt wherever the going gets tough. For example, on roads, paths, railroad ballast, and in construction. Because it can even withstand the extreme conditions in space, it is also used in lightweight structures for space travel.
    2:49 - Production of basalt fibers
    How are basalt fibers made? Basalt fiber production begins with crushing and cleaning the raw basalt. Then, in the smelting furnace, the rock is turned into molten basalt, or lava. The glowing melt is pressed through nozzles and pulled. Like spaghetti, only much finer to a diameter of 10 to 20 micrometers. This creates fibers that can be bundled and spun, either into a long yarn or into short fibers.
    3:25 - Advantages of basalt fibers for FASERFIX concrete
    Basalt fibers are now an integral part of our FASERFIX drainage channels.
    Advantages of basalt fibers
    ► Sustainable
    ► Resistant
    ► Recyclable
    ► Fireproof
    Basalt fibers now make FASERFIX concrete even more durable and safe. So what started thousands of years ago with a volcanic eruption is now in this drainage channel.
