It's time to sweat the small stuff. Researchers at Purdue University in Indiana, and in the UK are exploring new findings at the molecular level that could lead to both self-healing and more durable concrete. They're tapping into nanotechnology,defined by the National Nanotechnology Initiative as "the study and application of extremely small things and can be used across all the other science fields, such as chemistry, biology, physics, materials science, and engineering." It's becoming an increasingly important area for scientific development, especially for the concrete industry.

Here's a summary of the latest findings. Read More
