Martian soil - Wikipedia

Martian soil is the fine regolith found on the surface of Mars.Its properties can differ significantly from those of terrestrial soil, including its toxicity due to the presence of perchlorates.The term Martian soil typically refers to the finer fraction of regolith. So far, no samples have been returned to Earth, the goal of a Mars sample-return mission, but the soil has been studied remotely

Strength and Durability Properties of Granite

M. G. Shaikh (et al 2011) [3] has found that the mixes with the artificial sand with dust as fine aggregate gives consistently higher strength than the mixes with natural sand. The sharp edges of the particles in artificial sand provide better bond with the cement than the rounded part of the natural sand. It was found that the weight loss of artificial sand block is considerably same with
