What is it about?
The used LRS mapped the grain size distribution and morphology of the real lunar regolith. It was created for the purpose of studying the erosive effect of dusty regolith fractions on the moving parts of lunar landers and other mechanical equipment; therefore, it simulated well the behavior of regolith particles in relation to cement paste. The obtained results made it possible to develop preliminary compositions for “lunar mortars” (possible to apply in, e.g., 3D concrete printing) and to prepare, test, and evaluate mortar properties in comparison to traditional quartz mortars (under the conditions of the Earth laboratory).

Why is it important?
Analysis of locally available lunar regolith as the potential aggregate in concrete that was supposed to be produced on the Moon. The experimentally proven influence of lunar soil on the consistency of the low water/cement ratio mixes.
Perspectives
New area of application of concrete - as the extraterrestrial construction material.
