'Nature's antifreeze' provides formula for more durable concrete

Secrets to cementing the sustainability of our future infrastructure may come from nature, such as proteins that keep plants and animals from freezing in extremely cold conditions. CU Boulder researchers have discovered that a synthetic molecule based on natural antifreeze proteins minimizes freeze-thaw damage and increases the strength and durability of concrete, improving the longevity of new infrastructure and decreasing carbon emissions over its lifetime. They found that adding a biomimetic molecule—one that mimics antifreeze compounds found in Arctic and Antarctic organisms—to concrete effectively prevents ice crystal growth and subsequent damage. This new method, published today in Cell Reports Physical Science, challenges more than 70 years of conventional approaches in mitigating frost damage in concrete infrastructure. Read more.....
