I am going to demolish a garage where the interior ceiling is made of a material I do not recognize. It looks like wood strips or straw dipped in concrete.
Does anyone know what it is and how to handle the demolition waste?
If you read up a little, which I've done for an hour now, you see that träullit is used and has been used, among other things, as a plaster carrier on the outside of houses, but also in other places. As an acoustically dampening building element, especially good in swimming pools and such, as the cement content in the boards prevents growth due to the alkaline environment provided by the cement. It has also been used to build both entire exterior walls as well as interior walls with träullit, which are then just plastered; there are plastered houses from the 1950s with this construction. Träullit now has a system with thick whole wall elements that can be quickly erected, creating a complete house frame in a very short time. Ideally, this is plastered on the outside, and plaster or paneled interior becomes suitable.
Yes, it almost makes me tempted. However, I suspect that the square meter price deviates quite a bit from a timber frame with the same insulation value. Attaching to the walls will probably be just about as hopeless as with LECA and lightweight concrete.
Fire resistance and mold resistance should be two good features; heat storage and weight are two other features that can sometimes be desirable.
But well, if there will ever be an Atterfall house here, I will check if a träullit frame can be an alternative.
It appears to be a reinforced concrete beam at the top and vertical concrete columns between the elements. (Yes, of smaller dimensions then, so they end up inside the träullit wall).
