According to researchers from the US Aerospace Agency (NASA), humans can build bases on the moon with water-free concrete derived from the moon dust.
NASA wants to build a long-term base on the Moon that serves astronauts on space expeditions. However, the construction of permanent buildings on distant planets has a high price: to transport 1kg of material to the Moon, costing up to 50,000 - 100,000 USD.
On Earth, concrete is made of gravel mixed with water and cement. Recently NASA scientists have successfully studied a type of concrete mainly made from Moon dust replacing sandy soil and sulphurous interconnected from the Lunar soil.
To obtain liquid or semi-liquid surphur for adhesives, researchers must heat them to 130-140oC, then cool them. Concrete will then become as hard as stone and within an hour durable enough to be used immediately. With normal concrete, waiting time is 7 days, even 28 days of concrete to achieve the greatest strength.
Earlier this year, scientists successfully built water-free concrete using epoxy as a coating, but this type of concrete was not chosen to be based on the Moon due to its high transport costs.
