bioMason Grows Bricks Without Using Any Heat | Biomimicry | Scoop.it

"[...] bioMason grows bricks and masonry without using any heat.

[...] It starts by packing sand into regular molds, which are then inoculated with bacteria. The bacteria wrap themselves around grains of sand. Each grain acts as a nucleus and calcium carbonate crystals form around it. The bricks are then fed nutrient-rich water via an irrigation system for the next couple of days, speeding up the growth of the crystals which then fill the gaps between grains of sand. After four days, the bricks are strong, durable and ready to be used on the construction yard, and the water is then reused for the next set."
