Abstract:

Material source and environmental impacts are two major concerns in the application of conventional concrete technology in lunar base construction. In this study, the simulated lunar soil which is similar to lunar material in composition was adopted for small ceramic segment production. Compaction, resistance heating, and microwave heating technologies were applied to process the test specimens; furthermore, the produced test specimens were analyzed by scanning electron microscope and mercury intrusion porosimetry technologies. The test results reveal that under controlled heating temperature and heating time by resistance heating, the compressive strength of the test specimens with little or no water content has satisfactory outcomes. In addition, in considering the processing efficiency, the utility of the microwave heating process with regard to some constraints on the moon was also preliminarily compared with a traditional resistance heating process.
