Abstract: A microwave heating method and a cold press method are proposed as simple ways to produce construction materials on the Moon and Mars. The present experiment on the microwave heating method indicates that 5% of energy is expended on material manufacturing. This means 70 GJ of energy is required to make one cubic meter of material. The uniaxial compressive strength of the final material is found to be 1.2 × 105 kN/m2. The results of the cold press method show that a dry curing process is important to improve the compressive strength of the final material. The maximum compressive strength reaches 7.39 × 102 kN/m2. The microwave heating method can be used on the Moon, whereas the cold press method can be applied to both Lunar and Martian cases.
