“…In other words, KLS-1 had a G s value lower than that of lunar soil 14163 but similar to that of existing lunar simulants. A G s of 2.94 was obtained from crushed basalt alone without artificial additives or chemical processing because intrusive basalt in Cheorwon, Korea is known to have G s values between 2.7 and 3.0 (Min and Chin 1999;Nam et al 2008;Park et al 2014;Yeon et al 1999).…”

Lunar exploration, which slowed in the 21st century after the Apollo program, has seen more activity recently with the participation of Asian countries such as Japan, China, and India. Because lunar modules and rovers cannot be tested directly on lunar soil, these countries have developed lunar simulants. Simulating lunar soil is difficult and expensive because its formation mechanism and geotechnical behavior are comprehensively different from those of the terrestrial soil. Johnson Space Center Number One (JSC-1) and Johnson Space Center Number One A (JSC-1A), developed by the National Aeronautics and Space Administration, are the most widely used simulants. Korea has yet to succeed in developing a lunar simulant that meets international standards. The authors perform basic research on lunar simulant development based on basalt samples having similar chemical and mechanical properties to those of lunar soil, with reference to lunar soil data reported under the Apollo program. The resulting prototype is named Korea Lunar Stimulant-Type 1 (KLS-1). Compared with other lunar simulants [JSC-1 and Fuji Japanese Simulant 1 (FJS-1)], KLS-1 shows promise in terms of affordability and similarity to real lunar soil. As such, it is expected to find a wide variety of applications not only in space development projects but also in international research.

“…So, some methods to utilize clay mineral from CPR were suggested. [1][2][3][4][5][6] However, CPR has not been effectively utilized because of its low quality. It is thus highly desirable to find an effective utilization method of CPR.…”

It is important to find a possibility for utilizing coal-preparation refuse CPR generated from coal mines in terms of environmental and economic points of view. In this study, a possibility for manufacturing fired clay bricks FCBs by CPR instead of clay was investigated. Firing shrinkage ratio, compressive strength, and water absorption ratio of test samples manufactured using CPR in the open air were measured. It was found that firing shrinkage ratio and compressive strength decrease with increasing the addition amount of CPR, while water absorption ratio is almost constant under the entire addition amount ranges of that. The test sample manufactured was nearly similar to the 1st grade clay bricks of Korea Standard L ceramics 4201.
