Cast Basalt, Mineral Wool, and Oxygen Production: Early
In the terrestrial environment, transportation cost is the basic limitation on the use of building materials such as sand, cement, gravel, and stones. Because of transport cost, local materials are preferred over imported, higher-quality materials. This is apparently the case for lunar and martian outposts as well, and this fact is augmented by the need to transport as little technological ...

Cast Basalt
DEMECH is a pioneer in the manufacture of Cast Basalt tiles and cylinders in India since 1987. After selective quarrying, the volcanic rock is melted at a temperature of around 1500ºC and cast into molds or spun into cylinders. The castings so produced are then subjected to heat treatment cycles in special kilns to produce re-crystallized basalt.

The Effects of Mineral Variations on the Basalt Sintering
In ancient times, basalt was used to build rock walls, buildings, and foundations. In the early twentieth century manufacturers in Europe developed methods to cast basalt that resulted in materials that were strong, nonporous, and chemically inert. Basalt casting should be feasible on the Moon and Mars; however, it is extremely energy intensive.
