Daniel Mandler , a chemistry professor at the Hebrew University of Jerusalem, wants to turn it into bricks, in what could be a huge benefit for the planet. It would turn a useless pollutant into a strong, valuable building material , and reduce the cement industry's enormous carbon footprint .
He has already made prototype bricks in his laboratory . He adds a proprietary blend of ingredients to keep the salt from dissolving, grinds it, and compresses it into a brick that is many times stronger than cement .
There are still many technical challenges to solve and a lot of inertia to overcome in a construction sector that is slow to adopt new ideas, he says. But Professor Mandler is convinced that salt could become the building material of the future .
Thinking for a moment about two things: the amount of salt that accumulates around the world and the damage caused by cement production, we see why salt bricks are such an attractive proposition.
Cement production is one of the Phone Number List most polluting industries in the world, directly responsible for between 8-9% of carbon dioxide emissions worldwide. Manufacturers heat calcium carbonate to.
Salt bricks are a simple and sustainable , but so far unfunded, solution that kills two birds with one stone. They offer clear advantages. But they have not been tried or tested. And Professor Mandler has not yet found the funding necessary to make them a reality.
The manufacturing process is extraordinarily simple . They make a stainless steel mold, and in a very simple process, at room temperature, they mix the Dead Sea salt with 5% of different ingredients, crush them and compress them with about two tons per square centimeter of pressure. And that's it. Ready. Nothing else. If you compare it, for example, with cement, the carbon footprint here is almost zero
