I do not consider myself to be particularly sensitive to perception in order to confidently recognize the difference between concrete with and without Pneumatit. This does not mean that I would not feel differently about buildings made with Pneumatit-concrete. Whenever I enter the seed cleaning facility, I still have a very positive impression. The same feeling occurs when I enter the new building. However, I am not sure if I would be as confident in a blind test at another location. It doesn’t even have to be that way. For me, Pneumatit is a valuable addition and further development of the material concrete.
