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 …

Fused cast basalt ABRESIST® Wear Resistant Linings ABRESIST® fused cast basalt linings are a mineral based, wear resistant material that protects material handling and processing components conveying abrasive materials. The pre-engineered ABRESIST linings and tiles are produced by melting volcanic rock, then casting into shaped tiles or

melting properties undertaken in Britain by Roberts-Austen and Ru¨cker (1891) revealed the thermochem-ical complications arising from glass formation when basalt liquids are rapidly cooled. Barus' result was deemed to be too low because of basalt vitrification. Therefore, a value of 418 J/g was suggested by Bowen (1913) for the enthalpy of ...

 — Abstract The distribution of uranium between different phases of cast stone matrices fabricated by fusion of basalt and uranium-bearing SiO2-based collectors was investigated. It was found that matrices created by fusion of basalt with SiO2 consist of glass, quartz, and spinel as the main phases. A study of the physicochemical properties …

Special attention is devoted to their influence on the viscosity and crystallizability …

 — Melting phase relations of basaltic and peridotitic lithologies have been studied experimentally in multi-anvil presses up to the upper-lower mantle boundary (25 …

 — Basalt, a fine grained igneous rock, would be fine. It would still need quite a long cool down time. ... $begingroup$ Thanks for the correction. cast iron does have a lower melting point than pure iron. 13th century for a blast furnace is late medieval to early renaissance technology, so it still doesn't qualify as advanced technology. $endgroup$

Abstract—The distribution of uranium between diff erent phases of cast stone matrices fabricated by fusion of basalt and uranium-bearing SiO2-based collectors was investigated. It was found that matrices created by fusion of basalt with SiO2 consist of glass, quartz, and spinel as the main phases. A study of the physicochemical properties

 — Cast stone (CS) matrices were obtained by co-melting basalt and uranium-containing Al 2 O 3 at 1623 K in the air for 5 h.. Major phases of CS matrices were uranium-containing glass, plagioclase, and spinel. • The uranium leaching rate into water after 24-hour contact of CS matrices with H 2 O at 298 K was ~ 7.7∙10-6 g U/(g∙day).

 — Last year, PISCES made a similar pivot in its research approach, focusing on casting methods using Hawaiian basalt. Naturally, Kyla's knowledge of the field aligned with PISCES' casting research …

 — We report the structure, density, diffusivity, electrical conductivity and viscosity of a model basaltic (Ca11Mg7Al8Si22O74) melt from first-principles molecular …

 — 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 …

 — The product was basalt cast with the following dominant composition is MgO 5.244%, Al 2 O 3 21.295%, SiO 2 48.750, CaO 10.138%, Fe 2 O 3 11.019%, TiO 2 1.361% and Na 2 O 2.132%. ... The process of ...

 — Semantic Scholar extracted view of "Phase distribution of uranium in matrices obtained by co-melting basalt and uranium-containing aluminum oxide" by K. Martynov et al. ... The distribution of uranium between different phases of cast stone matrices fabricated by fusion of basalt and uranium-bearing SiO2-based collectors was investigated. It was ...

 — The possibility of manufacturing fibers directly from the basalt raw material is exploited for various applications: different production technologies allow basalt fibers to be obtained in two main categories: discrete fibers (rock wool, chopped, flakes, scales and powders) and continuous ones that can subsequently be woven into many commercial …
