[VIDEO] NASA Testing Concrete for Constructing Moon Base

Researchers are analyzing results of experiments done aboard the International Space Station to understand the performance of cement-based concrete in microgravity

Next to water, concrete is the most widely used material on Earth. In the future, it may also be equally useful off the planet—when humans construct a permanent base on the moon. Two experiments have taken place aboard the International Space Station (ISS) to see how concrete holds up in outer space. Researchers from Pennsylvania State University and NASA's Marshall Space Flight Center are analyzing the studies' results.
