![]() #CURE MY ADDICTION CHAPTER 1 CRACKED#This new NSF funding will help the team improve the processes that will allow for EMC to move more swiftly from the lab to construction sites.Ī new pathway for the material could also be used to fix cracked or fractured glass. ![]() ECM can also be produced at a low cost as the percentage of the enzymes is minute. It also does not require baking at high temperatures like a traditional brick does, and it can be made quickly, unlike the 28 days needed to cure concrete. Through extensive testing and experimentation, the research team found that ECM has "outstanding" compression strength, rivaling traditional mortar, making it strong enough to be used in the construction of buildings as compressive elements. ![]() Through this process, ECM can "heal itself" and fix cracks or other imperfections that may develop over time, retaining its strength through as many as six self-healing cycles. A sand slurry is also added, as well as a polymer, which holds the ECM together during its early stages, much like scaffolding does during the construction of a building. This reaction creates calcium carbonate crystals, which serve as ECM's main ingredient. ECM is made through a process involving an enzyme known as carbonic anhydrase - found in all living cells - that has the unique ability to react with CO 2 to rapidly remove the greenhouse gas from the atmosphere. In addition to their efforts to help mitigate the massive climate change impacts created by concrete, Rahbar and Scarlata plan to use the new funding to refine and optimize ECM and the processes to create it, and expand its use to different materials.īiological enzymes are catalysts that drive chemical reactions. ![]()
