Table 10 Summary table of existing results.
Research content | Research method | Main findings |
|---|---|---|
The effect of polypropylene fiber and EPS particles on the properties of lightweight soil32. | Orthogonal test SEM observation | The cement content has the greatest influence on the strength and the fiber can improve the crack resistance. |
Microstructure and strength characteristics of foamed lightweight soil33. | SEM observation Experimental analysis | The water-solid ratio affects the microstructure and strength—a denser pore structure yields higher strength. |
Mechanical properties of mycelium composite lightweight soil34 | SEM observation Regression analysis | The degree of mycelium colonization affects the mechanical properties, and the addition of aggregates can enhance the strength. |
Effect of silty clay on foamed lightweight soil35 | SEM observation Experimental analysis | Powdery clay doping and foam doping affect microstructure and macroscopic properties |
