Abstract: Using hydrothermal curing technology, basalt powder, calcium carbide slag, and desulfurization gypsum were employed as raw materials to prepare artificial stone granular materials. To investigate the durability of these materials made from solid waste, tests were conducted on water resistance, acid resistance, and freeze-thaw cycles under different calcium-to-silicon ratio(Ca/Si) conditions of the raw materials. Additionally, SEM microscopic characterization was employed to analyze the durability. The study utilized mass loss rate and strength loss rate as indicators to evaluate the durability of artificial stone granular materials. Test results indicate that the overall water resistance of the artificial stone granular material is good. Increasing the Ca/Si ratio of raw materials is beneficial for improving the water resistance of the artificial stone granular materials. When Ca/Si reaches 1.0, the softening coefficient can reach 0.894. Acid corrosion can result in mass loss and strength reduction of the artificial stone granular materials. Increasing the Ca/Si ratio of raw materials enhances the acid corrosion resistance of the artificial stone granular materials. Freeze-thaw cycles can induce cracks in the artificial stone granular material, leading to a reduction in compressive strength. When Ca/Si is 0.9 and 1.0, the artificial stone granular material exhibits the lowest strength loss rate of 18.7%, indicating relatively optimal resistance to freeze-thaw cycles.
