Construction of Concrete Structures on the Moon

这一研究讨论了月球材料在月球上的未来水泥生产的潜在用途。一般来说，月球材料有低钙氧化物浓度，可能不适合于水泥形成。无光泽的、月球异常岩石（17%的CaO）和月球basalt（12%的CaO）已经成功地用于制备水泥材料。Hokkaido Anorthite consists占钙氧化物的16%，并考虑了拟议的月球水泥生产研究的候选材料。一种能够产生热量至1600℃的电动家具，被用作类似于北海道讽刺的几个长凳燃烧的方法。日落温度和持续时间为145摄氏度，一小时，尊重。两种带有2670至5000米的月球水泥的类型，由Blaine Wvere制造。T.开发的传统湿混合过程和干燥混合/蒸汽注入（DM/SI）方法D.

This study discusses potential utilization of Lunar materials for future cement production on the Moon. In general, lunar materials have a low calcium oxide concentration and may be unsuitable for cement formation. Nonetheless, lunar anorthite rocks (17%CaO) and lunar basalt(12% CaO) have been successfully used in formulating a cementitious material. Hokkaido anorthite consists of 16% of calcium oxide and is considered a candidate material for the proposed lunar cement production study. An electric furnace capable of generating heat up to 1600℃ was used to conduct several bench burns using Hokkaido anorthite as simulant. The sintering temperature and duration were 145O℃ and one hour, respectively. Two types of lunar cements with finess ranging from 2670 to 5000 Blaine wvere made. The conventional wet mix procedure and the Dry-Mix/Steam Injection (DM/SI) method developed by T. D. Lin were applied to make a series of 4cm mortar cubes for compression tests. The wet-mix cubes developed 2.9N/mmィイD12ィエD1 after 7 days of curing in a moist room while the DM/SI cubes developed 21.9N/mmィイD12ィエD1 after 24hours of steaming at 170℃. Scanning Electronic Microscopic analysis and X-Ray diffraction analysis were performed to determine the morphology and chemical compositions of the obtained hydrates.
