IN THE TRANSITION from fossile fuels to renewable ones, it is, to put it mildly, contradictory that humanity continues to use cement. Cement foundations for houses are almost standard in Sweden today, yet cement is a very energy-intensive product to produce, the cement slab as a house foundation is a fatally failed construction that is neither easy to demolish nor to rebuild. What to do when you want to put new pipes in the plate? It turns out to tear up floors and tiles and mill new grooves and cast in new pipes… Roads and bridges are built of cement. The new route of the E4 past Uppsala is a cement slab. Now it turned out that it did not last for 40 years as it was said and was also a very noisy coating. It only lasted almost 10 years, and now you have had to pave it with asphalt anyway…
