Using solid waste such as engineering musk， carbide slag， and desulfurization gypsum as raw materials， the solid-waste based artificial crushed stone was prepared through hydrothermal curing technology. The effect of hydrothermal curing conditions on the mechanical properties and microscopic pore structure of the artificial crushed stone was studied. Additionally， experiments on the crushed stone production process of the solid waste-based artificial crushed stone were conducted， and the physical properties of artificial crushed stone and natural crushed stone were measured and compared. The results showed that the compressive strength of the solid waste-based artificial crushed stone initially increased and then decreased with rising reaction temperature and time， while it decreased with increasing dry density and decreasing maximum particle size after sieving. Specimens prepared from wet soil exhibited lower compressive strength than those from dry soil due to uneven contact area and insufficient hydrothermal curing. Under the crushed stone production process， the water absorption rate of the solid waste-based artificial crushed stone was approximately 21.2%， 4.7 times that of natural crushed stone， and its crushing index was about 27.1%， 3.8 times that of natural crushed stone.
