    Experimental research on resource utilization of iron tailings powder in backfilling engineering by Guo-Hua Yuan, Yun-Shi Yao, Pu-Gang Zhang, Wei-Guo Hao, Kun-Peng Huang, Jin-Li, Qing-Fang Shang

    Published 2025-01-01
    “…The results show that under the premise of keeping the fluidity constant, the strength of the ITP slurry increases with the increase of the curing agent content; At the same strength, the water consumption significantly affects the fluidity; When using 8%~16% different curing agent dosage, the expansion degree is 280 mm ~ 600 mm, the wet density is 1.9 g/cm3 ~ 2.1 g/cm3, the 28d strength after curing is 1.4 MPa ~ 3.7 MPa, and the stone rate is greater than 92%; The ITP slurry prepared by vibration mixing with a mixing time of 120 s and the amount of curing agent at 8% meets the engineering application requirements of 7d strength of 0.6 MPa and expansion of 250 mm. …”
