Traditional
concrete comprises a binder — cement and water — mixed with aggregates.
While some parts of the Moon may have water, that resource may be more
valuable for astronaut’s consumption rather than building structures.
His
research shows that those astronauts can turn to a new type of
water-less concrete that uses lunar soil as the aggregate and sulfur as a
binding agent.
Toutanji,
who is also chair of the civil and environmental engineering department
at U A Huntsville, has spent years studying the characteristics of
cementitious materials, said he anticipates concrete to play a major
role in constructing facilities on the lunar surface to survive the
harsh environment on the Moon’s surface.
NASA is searching for a means to use resources that are available from the surface of the moon, according to Toutanji.
“The difficulty of transporting materials from Earth will place a premium on resourcefulness and ingenuity,” he said.
