Collapse inhibition mechanism analysis and durability properties of cement-stabilized Pisha sandstone

Green and Low-Cost Modified Pisha Sandstone Geopolymer Gel Materials for Ecological Restoration: A Phase Review

“…However, the performance of the material decreased significantly when the amount exceeded 30%. Geng et al [89] studied the effect of cement amount on the properties of PS. The results showed that with the increase in cement incorporation, the porosity of PS gradually decreased, the cohesion tended to increase, the material tended to be brittle, the pore deterioration of PS under freeze-thaw action was reduced, and the frost resistance was significantly improved.…”

“…Based on the above research, materials for dam engineering were prepared and applied in the Erlaohuo gully dam project of Ordos Jungar Banner to verify the feasibility of PS-modified materials in the engineering of check dams in Pisha sandstone regions [72,97]. On the other hand, PS-based cement materials used in the construction of check dams and slope engineering have also been widely studied [36,89,93,94]. However, even though concrete has desirable mechanical strength, there are limitations to its durability performance.…”

“…In addition, Zhu et al [91,99] prepared compound soil by mixing fly ash with PS cement soil through alkali excitation technology. It was concluded that fly ash significantly improved the mechanical properties and microstructure of PS cement On the other hand, PS-based cement materials used in the construction of check dams and slope engineering have also been widely studied [36,89,93,94]. However, even though concrete has desirable mechanical strength, there are limitations to its durability performance.…”
