The study examines how dry-wet cycles and fly ash impact the effectiveness of magnesium phosphate cement (MPC) in solidifying zinc-contaminated soil, which is important for soil remediation.
It involved subjecting cylindrical samples to varying numbers of drying-wetting cycles (0 to 10) and different fly ash contents, measuring mass loss, compressive strength, and zinc leaching.
Results showed that zinc leaching concentration initially increased with the number of cycles but plateaued after three cycles, while the optimal fly ash content for strength and durability was found to be around 20%.
