Beer and brick have both been essential to humanity for thousands of years , dual column that helped us build the societies we know today . Now , scientists have combine them , fortify brick with grains will over from brewery to create brick that keep a construction best insulated . Turns out beer really can keep you strong on a cold day .
enquiry engineer foundthat bricks made with 5 % spend brewing grains were nearly 30 % better insulators , and just as strong as traditional brick . The improved thermic functioning comes from the tiny pockets of air trapped in the clay when the grain are mix in . Polystyrene pellets achieve the same effect , and are used in some bricks presently . But synthetic cost money to raise , while spent grains are either feed to livestock or , more often , send to a landfill . And beer ’s worldwide popularity means there ’s a nearly limitless supply of leftover ripe for the pickings .
There is one significant drawback , however : the foul-smelling fetor of moist , fermented food grain . The smell disappears once the bricks have been dried in a kiln , but during production the smell was so overwhelming some investigator abandon the experiment .
Still , a significant betterment in thermal efficiency , requiring nothing more than beer leftovers , could be tempting enough for brickmakers to check their nose . Perhaps shortly your theater will fight off winter ’s shivering just like you do — with the delicious fortification of a golden brew . [ Journal of Materials in Civil EngineeringviaNew Scientist ]
